Rectangle, square, triangle, trapezium and others - geometric shapes from the exact science section. The pyramid is a polyhedron. The base of this figure is a polygon, and the side faces are triangles with a common vertex, or trapezoid. For a complete presentation and study of any geometric object, mock-ups are made. Use the most diverse material from which the pyramid is made. The surface of a polyhedral figure, developed on a plane, is called its development. The method of converting flat objects into volumetric polyhedra and certain knowledge from geometry will help to create a layout. It is not easy to make reamers from paper or cardboard. You will need the ability to perform drawings according to given dimensions.
Modeling and implementation of multifaceted three-dimensional geometric shapes is an interesting and exciting process. From paper, you can make a large number of various layouts. For work you will need:
First of all, let's define what the pyramid will be. The development of this figure is the basis for the manufacture of a three-dimensional figure. Doing the job will require extreme precision. If the drawing is incorrect, it will be impossible to assemble a geometric figure. Suppose you need to make a layout of the correct
Any geometric body has certain properties. This figure has a base and its top is projected into its center. Selected as the basis This condition determines the name. The side edges of the pyramid are triangles, the number of which depends on the polyhedron chosen for the base. In this case, there will be three. It is also important to know the dimensions of all the constituent parts of which the pyramid will be composed. Paper sweeps are performed in accordance with all data of a geometric figure. The parameters of the future model are negotiated in advance. The choice of material used depends on these data.
The basis of the model is a sheet of paper or cardboard. Work begins with a pyramid drawing. The figure is shown expanded. A flat image on paper corresponds to pre-selected dimensions and parameters. has a regular polygon as its base, and its altitude passes through its center. Let's start with a simple model. In this case, it is a triangular pyramid. Determine the dimensions of the selected shape.
To build a net of a pyramid, the base of which is a regular triangle, in the center of the sheet, using a ruler and a pencil, draw the base of the given dimensions. Next, to each of its sides, we draw the side faces of the pyramid - triangles. Now let's move on to building them. The dimensions of the sides of the triangles of the lateral surface are measured with a compass. We put the leg of the compass at the top of the drawn base and make a notch. We repeat the action, moving to the next point of the triangle. The intersection obtained as a result of such actions will determine the vertices of the side faces of the pyramid. We connect them to the base. We get a drawing of a pyramid. For gluing a three-dimensional figure, valves are provided on the sides of the side faces. We finish drawing small trapeziums.
Cut out the outline with scissors. Gently bend the scan along all lines. We fill the trapezoid valves inside the figure so that its faces close. Lubricate them with glue. After thirty minutes, the glue will dry. Volumetric figure is ready.
First, let's imagine what a geometric figure looks like, the layout of which we will make. The base of the chosen pyramid is a quadrilateral. Lateral ribs - triangles. For work, we use the same materials and fixtures as in the previous version. The drawing is done on paper with a pencil. In the center of the sheet, draw a quadrilateral with the selected parameters.
Divide each side of the base in half. We draw a perpendicular, which will be the height of the triangular face. With a compass solution equal to the length of the side face of the pyramid, we make notches on the perpendiculars, setting its leg to the top of the base. We connect both corners of one side of the base with the resulting point on the perpendicular. As a result, we get a square in the center of the drawing, on the faces of which triangles are drawn. To fix the model on the side faces, draw auxiliary valves. For reliable fastening, a centimeter-wide strip is enough. The pyramid is ready for assembly.
The resulting pattern of the figure is cut out along the contour. Bend the paper along the drawn lines. The volumetric figure is collected by gluing. Lubricate the provided valves with glue and fix the resulting model.
After completing a simple polyhedron model, you can move on to more complex geometric shapes. The development of a truncated pyramid is much more difficult to perform. Its bases are similar polyhedra. The side faces are trapezoids. The sequence of work will be the same as that in which a simple pyramid was made. The sweep will be more cumbersome. To complete the drawing, use a pencil, a compass and a ruler.
The development of a truncated pyramid is performed in several stages. The side face of the truncated pyramid is a trapezoid, and the bases are similar polyhedra. Let's say they are squares. On a sheet of paper, we draw a trapezoid with the given dimensions. We extend the sides of the resulting figure to the intersection. The result is an isosceles triangle. We measure its side with a compass. On a separate sheet of paper we build which will be the measured distance.
The next stage is the construction of the side edges that the truncated pyramid has. The sweep is performed inside the drawn circle. The lower base of the trapezoid is measured with a compass. On the circle we mark five points that connect the lines with its center. We get four isosceles triangles. With a compass we measure the side of the trapezoid drawn on a separate sheet. This distance is set aside on each side of the drawn triangles. We connect the obtained points. The side faces of the trapezoid are ready. It remains only to draw the upper and lower bases of the pyramid. In this case, these are similar polyhedra - squares. Draw squares to the upper and lower bases of the first trapezoid. The drawing shows all the parts that the pyramid has. The sweep is almost ready. It remains only to finish the connecting valves on the sides of the smaller square and one of the faces of the trapezoid.
Before gluing the three-dimensional figure, the drawing along the contour is cut out with scissors. Next, the scan is carefully bent along the drawn lines. Mounting valves are filled inside the model. Lubricate them with glue and press them to the edges of the pyramid. Let the models dry.
Making three-dimensional models of geometric shapes is an exciting activity. To master it thoroughly, you should start by performing the simplest scans. Gradually moving from simple crafts to more complex models, you can begin to create the most intricate designs.
Most of the blocks will be stitched according to the patterns found in two places. The beauty of these places is that there are colored drawings of blocks. And nothing more.The rest of the blocks - scraped in the bottom of the barrel.
Assembly - according to pattern-stencils. This is explained by the fact that I have a set of fabrics at my disposal, consisting of squares of 25 cm X 25 cm (10 inches by 10 inches).
**************************************************
BLOCK 1.STAR FROM RHOMBOS. THREE COLOURS.
This star is widely known. In the English-speaking environment, she has some name like "Sarah Connor Star", "Star of Oklahoma" or "300 Heroes Victory Star at Blue Stone Mountain". I do not consider it necessary to look for this name and give it: this does not mean anything to Russians.
(Found the name. Guessed: "Star of Virginia"))))).
The drawing below is only needed if you need a block of a certain size. (All this geometry made it possible to draw only one, but important conclusion: with the desired block size of 36 X 36 cm, the length of the side of the rhombus is 5 cm. And that's all. If the size of the block is not important, then the drawing is not needed, since the side of the rhombuses is equal to the legs of right triangles and square).
Four types of fabric are needed:
"1" - an asterisk in the center, 8 rhombuses;
"2" - the central part, 16 diamonds;
"3" - acute angles of rays, 8 rhombuses;
background fabric.
It is possible to cut from strips: strip from fabric "1" + strip from fabric "2" (see pink element); fabric strip "2" + fabric strip "3" (see yellow element).
But I have fabric in sets: small squares. Only a cut of individual parts is possible. Alas!
Three types of rhombuses are prepared, and the yellow squares are the filling of the space between the corners of the star, the background fabric. Only 8 squares. Where the pattern requires triangles from the background fabric, it is better to sew in the squares and then cut them off.
Because the rhombus - a very insidious part to connect, you need to perform a number of mandatory steps.
1) On the wrong side of each rhombus, applying a pattern, mark the points of the corners with a pencil or marker.
The numbers are my dimensions for cutting. You don't have to pay attention.
2) Connecting individual rhombuses, pierce these points, and only then connect the parts with a pin for further sewing on a typewriter.
If you connect rhombuses by eye, then the number of successful connections will be correlated with unsuccessful ones as 1:5. Checked.
3) Connecting the already sewn parts, you need to pierce the seam at the first and second parts through and through, retreating to the width of the allowance (red pin), and only then chop off the parts with pins for further work on the typewriter.
When connecting a star with squares from the background fabric, you need to: 1) connect each side separately (never turn at corners!) and 2) bring the seam to the point on the diamond that was marked with a marker.
The order of assembly is dictated by the logic and structure of the block.
1) Connect diamonds from fabric "1" with diamonds from fabric "2" - 8 parts; and rhombuses from fabric "2" with rhombuses from fabric "3" - also 8 parts;
2) connect the "petal" or "edge" of the star - 8 times;
3) connect 2 "petals";
4) connect sewn 2 "petals" and 2 "petals", get a half-star - 2 parts;
5) connect 2 half-stars - you get a star;
6) connect the star with the details from the background fabric in any order.
A different order is possible if you don't mind cutting the background fabric.
Wrong side.
When smoothing, simple and general rules apply: smooth the allowances from converging seams in different directions (here it is important when connecting rhombuses), iron the allowances on a darker fabric (here the allowances from the background fabric are ironed on the dark details of the star).
Process the point in the center where 8 corners converge, again according to the general rules: cut the seams to the very point of connection, put a finger into this “bud” and twist it. Allowances will lie optimally, and there will be no lump.
Star ready. It is beautiful in any performance: blue, yellow, red, multi-colored. Unbeatable block.
BLOCK 2. STAR FROM 12 RAYS (8 + 4). June Star.
Why "Star of June"? Because it was made in June. I don’t know the English name, and I don’t want to know.
Star in different lighting.
The peculiarity of this and similar stars is that the distance between the vertices of the rays both horizontally, vertically, and diagonally should be the same (the diagonal is highlighted with a dash). The calculations are simple: the 1st segment is the leg of an equilateral right triangle, the 2nd segment is its hypotenuse, the 3rd segment is again the leg.
Fabric selection is simple: the first pair (dark, light), the second pair (dark, light), one or two background fabrics. This version of the star has 2 background fabrics, although there is only one in the diagram on the Internet.
A quarter of the drawn scheme will serve as a pattern.
This star does not obey any methods of quick assembly. Only element-by-element connection! The only thing that this star allows is the division of the block into 4 squares, which are assembled at the very end of the sewing.
Details are cut at different angles and, accordingly, are strongly deformed after sewing on a typewriter. The second square of the drawn scheme can serve as a pattern for trimming stitched elements.
Aligned elements.
How to bend allowances? With so many parts of different geometry, not all traditional rules apply. For example, a way to smooth out allowances only on the dark side is completely unthinkable.
The photo shows that the main desire was to bend the allowances in different directions, which is especially important when connecting the corner-corner, when a thick seam is obtained.
Capricious star! To avoid distortions you need:
1) make large allowances up to 1 cm and even a little more, since the stitched elements need to be aligned during work;
2) on the wrong side of each detail, mark the corners with a marker or pencil, and stitching the details, pierce these points first, and then chip the details with pins (all the details are different, the angles are different, there is nothing to focus on!).
But the harmony of the completed star will pay for everything.
*********************************************************************************
BLOCK 3. A STAR WITH INTERWORDED RAYS.
This star has no "volume", but there is another very interesting effect - the interlacing of details. That's what makes her interesting.
In order for such a pattern to form in the center, it is necessary that the parts of the side of the block correlate as follows: 3, 4, 3. For example, the side of the block is 30 cm, we carry out simple calculations: 30:10 \u003d 3 cm, 3 cm is the length of the conditional units; 3x3 \u003d 9 cm, 3x4 \u003d 12 cm. This means that the side must be divided into segments 9 cm, 12 cm, 9 cm.
In order to form a pattern, it is necessary to select 8 fabrics + background fabric. And nothing else. (In 4 fabrics, the block is inexpressive, in 2 - even better, but boring).
The simplicity of the block lies in the fact that all the details are right triangles. This means that you do not need to align the elements during sewing. But this simplicity is deceptive.
First, all triangles are different sizes. In the diagram above, different triangles are marked with a red felt-tip pen; it can be seen that 7 types of different right triangles are required.
From each fabric (except for the background) it is necessary to cut out 3 triangles: for 4 types of fabric - one set, for the remaining 4 - a different set (see the triangles in the center - they are different!).
And the connection of details is full of surprises. The triangles of the star are connected to each other by only part of the side. These funny points are marked below.
(Of course, you can simplify the assembly by cutting the triangles into pieces, but this will not add beauty).
This puts forward a number of requirements for cutting and sewing:
1) on the wrong side of all triangles of the star (excluding corners) you need to put a triangle pattern and mark the corners with a pencil or marker; Connecting seams should only be brought up to these points;
2) and on those triangles that are connected to the neighboring triangle by an incomplete side, put the points of their connection; on my diagram, these are large purple, yellow, blue, light green, in the center - small red, lilac, orange, blue. Do not connect them by eye!
The assembly is not easy, it looks like a puzzle. One of the possible options:
The assembly of each star gives the master a special mood. This one brings satisfaction from solving a complex geometric problem. And admiring it is similar to the joy of the "five" in mathematics.
*********************************************************************************
BLOCK 4. STAR WITH SHARP RAYS.
The peculiarity of this star is sharp rays. This is achieved simply: when drawing a sketch, you need to divide the side into 3 equal parts. (The previous star was divided into three parts with a ratio of 3:4:3. You can compare the proportions).
The complexity of making this star is already visible in the figure: 1) very sharp corners of triangles, 2) convergence of 16 (!!!) corners at one point.
When connecting the edges of the rays, it is better not to trust the eye. It is necessary, having previously drawn points of corners on the wrong side of the details, to connect these points first (see red round pins) and only then prick pins for sewing on a typewriter.
It is better to overdo it, to be safe, than, having spent time and work, to end up with a dubious product.
Techniques, techniques that facilitate work can be used when connecting corner squares (those with "butterflies").
Since 16 corners converge at one point, as already mentioned, it is not necessary to continue the seam to the edge of the fabric, connecting the edges of the star. You should stop at the marker point applied on the wrong side.
The photo shows that 8 corners already create enough mess, a kind of "bunch" of allowances.
How to smooth out allowances? The star itself suggests the only option. There are 16 corners in the center. You can straighten them by opening the seams to the center and "twisting" the allowances in one direction. And, having twisted the allowances of the edges, the rest of the allowances should be smoothed out so that the edges are "pulled".
Here is such a star ... Sewing is not difficult. But you need to prepare for the imperfect convergence of 16 corners. The seam is so thick that the foot of the machine itself jumps and shifts the connection point.
I would call this star - intriguing ... She, like a cat, walks by herself, sews herself together, behaves as she pleases.
*********************************************************************************
BLOCK 5. STAR WITH BROKEN FACETS.
In order to sketch this plump star, you need to divide the side of the square into 4 equal segments.
And again, you need to tighten what needs to be tightened, and relax what needs to be relaxed: again 16 corners at one point!
The star looks complicated, but you only need 4 types of fabric + background (I have 2 background).
The triangles are different, the angles are different, and you should repeat the already familiar procedure: draw patterns on the wrong side, paying special attention to the points that indicate the corners of the triangles.
No matter how tedious and hard it is, it must be done. It can be seen here that when connecting triangles with different angles, allowances of different sizes come out beyond the border of the stitched line. They cannot be guided when sewing. Therefore, you need to pierce the points of the corners of the stitched triangles (yellow round pins) and then fix the details.
The asterisk itself suggests the assembly option: it is optimal to sew along the edges.
Then quarter squares.
The allowances should be smoothed in the same way as with the 4th star: open the seams to the center, press the center, turning the allowances in one direction, and then follow the way the allowances of the rays lay. And they will lie either clockwise or against.
This star is simple. Calm. Very easy to assemble and gives peace of mind.
BLOCK 6. PIVOT.
Small rest block. It is good to sew when you are tired of calculations and complexity. Simple simplicity.
*********************************************************************************
BLOCK 7. BOW WITH LONG RIBBONS.
This is such a cute bow. The cut and assembly are clear at a glance.
Let's say the side of the square is the base of this block - a. Then you need:
1) 7 squares of light fabric with a side ( a + allowances);
2) 4 squares of dark fabric;
3) 3 large squares of light fabric;
4) 2 large squares of dark fabric;
5) 5 large squares from the background fabric;
6) 6 squares from the background fabric;
7) 2 rectangles from the background fabric with sides ( a+ allowances) and ( 2a+ allowances);
8) 2 background fabric rectangles with sides ( a+ allowances) and ( 5a+ allowances).
(The rectangles from the background fabric can be replaced with squares, then point 6 will change. You will need 20 squares).
Large squares appear due to the possible cut option in this case. You need to cut out large squares, lay them on top of each other, stitch along the perimeter, and then cut them diagonally. The result is squares of two multi-colored triangles.
Then the squares need to be ironed and aligned. How to calculate the side of a large square? The diagram shows that its side is: the diagonal of the desired square + 2 diagonal allowances + 1 cm for alignment.
It is better to slightly increase the side of this large square, and then cut off the excess, aligning the resulting two-color squares.
The assembly is very simple: sew the parts horizontally (or vertically), then sew the resulting stripes. The only awakening of the brain is when smoothing out allowances: one strip - to the left, the next strip - to the right ...
Here's a bow. Unfortunately, the thought comes late: it was necessary to use three fabrics, then the "weaving of ribbons" would be more expressive.
(The geometry is slightly broken, because there are allowances around the perimeter, which will then disappear).
*********************************************************************************
BLOCK 8. FOUR LOOP. Or: DOUBLE BOW.
In the original, the block looks like this (see below). Execution in 8 types of a fabric is possible - for each eyelet the set.
But I will sew according to this pattern: 2 identical loops + a highlighted middle.
At the heart of the block diagram is a square. Need to prepare:
1) very dark fabric - 2 large squares;
2) dark fabric 1 - 1 large square;
3) dark fabric 1 - 6 small squares;
4) dark fabric 2 - 1 large square;
5) dark fabric 2 - 6 small squares;
6) light fabric 1 - 1 large square;
7) light fabric 1 - 4 small squares;
8) light fabric 2 - 1 large square;
9) light fabric 2 - 4 small squares;
10) background fabric - 2 large squares;
11) 4 small squares.
Large squares are needed to save time when making two-color squares consisting of triangles. (See block 7 a little higher - there is a cut and calculation).
After working with large squares, the blanks look like this:
The block is prepared for assembly on a typewriter.
The final block.
*********************************************************************************
BLOCK 9. STAR IN A CIRCLE.
Here is such a star. Calm, laconic, restrained. So I want to say - educated, intelligent. Indeed, nothing more. The virtue of simplicity. Intellectual Star. From a good family. European.
The scheme is already familiar: the distances between all the rays of the star (both vertically, horizontally, and diagonally) should be the same. That is: leg, hypotenuse, leg.
Fabrics: 3 + background (I have 2 background, triangles in the center).
Cut - according to patterns of details. A pattern can serve as a part of a diagram drawn in full size.
I did not see any methods of simplifying the cut. (But that doesn't mean they don't exist.)
All details must be made in 4 copies, only large triangles (I have green ones) - 12 pieces.
The assembly of the block is arbitrary. At me - on sectors. Each sector is a continuation of the sides of the triangles in the center. There are 8 sectors in total, 4 of each type.
An assembly of sectors with dark background triangles in the center.
Assembly of sectors with a light triangle in the center.
Then collect 2 sectors.
4 each. And finally, the last seam and final assembly.
Wrong side. The location of the allowances is chaotic. But, however, not unsystematic. The main desire was to distribute the allowances of converging seams in different directions.
Here is such a star. A star for calm contemplation, reflection, attempts to think about the questions of the universe: what is a person, how long does the light of distant stars reach the Earth, where paired socks disappear after washing ...
*********************************************************************************
BLOCK 10. DUTCH ROSE.
The block diagram is complex and simple at the same time. On the one hand, all the segments inside the block are the same: both the sides of the squares and the sides of the rhombuses. On the other hand, it is difficult to calculate the circuit if you need a blocka certain size.
I failed because I forgot how to solve equations with a square root. Therefore, they simply cut rhombuses and squares with a side of 5 cm. The size of the block in this case is as follows: 34 cm x 34 cm. . (You can sew without stencils, and without drawings, since the dimensions of all parts are known).
If the block size does not matter, then the calculations are simple: see the Pythagorean formula. It will help to calculate the length of the two central segments of the side of the block (that is, the hypotenuse of a right triangle.
The acute angle of the rhombuses is 45 degrees.
Croy, on the contrary, gives joy, speed, ease. Stripes, then details.
It is necessary to cut out:
1) rhombuses from light fabric - 12;
2) diamonds made of dark fabric - 12;
3) rhombuses made of very dark or contrasting fabric - 8;
4) squares from the background fabric - 28 (or 8 and 20).
You will have to assemble the block in detail and scribble each seam separately. Otherwise, it's impossible. Or rather, it is possible, but by cutting the background squares.
With such an assembly, it makes no difference where to start. The choice fell on work from the center.
This "Dutch rose" never ceases to please with surprises: there are many points where the corners of 3, 5, 6 parts meet. Therefore, you need to strive to smooth out the allowances around these points in different directions.
So there you are, little scarlet flower!
The Diamond Star block is one of the most beautiful star blocks. It may consist of only eight diamonds or many diamonds, but the assembly principle will be general in all cases. In English-language sources, such a block is most often called "Lone Star".
The "Rhombus Star" block can be sewn in two ways: simply by cutting and connecting the rhombuses one at a time or using the "From Stripes" technique. Our master class will tell you in detail how to sew a Diamond Star block with your own hands and teach you how to use stripes to make other patterns.
If you want to sew a star from small scraps of fabric, you will need a diamond pattern with a sharp 45 degree angle.
For the "strip" technique, it is necessary to cut strips of the same width. Depending on the color scheme of the block, you will need a different number of stripes of each color. When cutting diamonds from stripes, you will be left with a few extra triangular parts that can be used for a product with a Diamond Star block or set aside for future projects.
We will show how to sew a star from three rows of diamonds, but the number of such rows may be different. In this case, the details of the block are cut out from strips that are sewn not from two, but from a larger number of colors.
So, let's sew the Diamond Star block with our own hands!
For a block about 22x22 cm in size, you will need:
Sew green and white stripes and white and yellow stripes.
Iron the allowances towards the colored fabrics. Trim the total width of the strips to 6cm (3 for each color).
Cut rhombuses from the strips, drawing the fabric, as shown in the photo. The straight side of the rhombus is 6 cm. Four rhombuses should be tilted in one direction, four in the other.
You will get eight diamonds from each strip and three extra triangles.
Lay the diamonds with green details in the center of the star, as shown in the photo.
Sew together a rhombus with a green part and a rhombus with a yellow part (one ray of a star). It is necessary to combine the place where the flowers join in the diamonds (in the center of the diamonds) at the seam level, as shown in the photo. Chip or sweep the first pair, open it and check the correct fit. In the future, also chip or sweep each pair of parts.
Straighten out the details. Lay out a block of stitched beams.
Sew two beams, make sure that the allowances are laid out in different directions. Check the matching of colored elements.
Lay out the block of 4 pieces. Adjust the details.
Attach the background squares to the star, check the size of the squares.
Spread the seams in the corners of the star for 3-4 stitches. Sew the squares on one side first, stopping the stitch exactly at the open seam of the star.
Unfold the piece and sew the second side of the square. Iron.
Iron the allowances of the square depending on the color scheme of the block - on the darker side.
Trim the block, bringing it to the shape of a square.
Decor.
Decor home page shops simple, discreet, concise. The first thing that catches your eye is a sign that shows boxes with puzzles.
After a couple of minutes, it changes and a very profitable proposition.
It is very easy to navigate the site, in the upper left corner is located menu, which includes the main sections.
Range.
The online store offers 2 types of original puzzles: Challenging Puzzle and IQ PUZZLE.
IQ PUZZLE- a series of 21 puzzles of varying difficulty. The figure can be assembled from 4-10 parts. The cost of one copy is 250-300 rubles.
*Puzzle solving does not require professional knowledge and skills.
At the moment, only 16 types are presented in the store, I suggest that you familiarize yourself with them.
But I know about the existence of other puzzles, for some reason they are not yet on sale.
Series Challenging Puzzle- a novelty of the store and at the moment the manufacturer has developed only 5 types of puzzles of this type.
If only one correct figure can be assembled from IQ PUZZLE parts, then from the Challenging Puzzles you can get as many as three different figures, therefore the cost is an order of magnitude higher - 400 rubles.
Making an order.
If you have decided on the order, then send the selected items to the basket. When choosing one or another puzzle, you will be prompted to immediately go to the basket, or continue the search.
Be sure to carefully check the order, especially the quantity and total amount, if everything is correct, then hurry up to click on "checkout". You will see a simple, standard form in which you must specify your full name, phone number for communication, e-mail, select a delivery method, address, payment method.
Accepting orders 24/7! Very convenient, isn't it? After registration on the site, the manager calls back and clarifies the order and other nuances.
Payment, delivery.
You can pay for the order using bank cards, or in cash upon receipt.
Residents of Moscow can pick up the parcel from the warehouse on their own, other buyers can use the courier service or the Russian Post.
Have you noticed that the amount of courier delivery does not differ from the amount that you need to pay if you choose Russian Post?
Carefully study the list of cities to which this applies.
Eh ... what a pity that my city was not on the list, so I had to arrange my parcel through the PR, which means that the delivery time increased by 2-3 days.
My order:
I received my parcel at the Russian Post office. She got to my city within a week.
Upon receipt, the puzzles were in a small cardboard box.
It also housed 2 ordered IQ Puzzle "Rhombus" and "Tree". Branded boxes are the size of cards, so you can always take puzzles with you and captivate a group of friends with them.
On the front side there is an image of the finished figure.
Boxes with puzzles are decorated in black and orange colors, the design is discreet, but not without a drop of positive! When opening the box, on the top, inner edge, we see quirky emoticons that will make anyone smile back.
The puzzles themselves are enclosed in zip-lock bags, in which I keep to this day, not a single detail will definitely be lost.
The puzzles I have chosen are of medium difficulty, they have 6 and 8 pieces of different shapes, which are made of durable, dense plastic in the same color scheme. The quality is on top, the surface is smooth, when fully assembled, they stand up to each other - millimeter to millimeter, there’s nothing to complain about.
If you accidentally scattered the contents of the package (or the children helped you in this matter), then on the back of the package you can peep from which puzzle which puzzle.
Also on the reverse side you can find the manufacturer's contacts and age restrictions 16+. But personally, I strongly disagree with him. Puzzles are great for developing logic, memory, so you can also offer a child to assemble a figure. I think that such puzzles can be a great gift for schoolchildren for any holiday.
And now the most interesting, I will tell you how I collected the figures.
IQ Puzzle "Wood".
This puzzle has 6 pieces. I started with it, since there are fewer parts than in the second one, so it seemed that I would assemble it faster.
The process itself is very exciting, I went through, rearranged, turned over the puzzles for about 30 minutes and all to no avail! And I even thought that perhaps the wrong parts were put into my set, double-checked, compared them with the image on the box, everything is in place, they didn’t confuse anything. I decided to try again and after 20 minutes I collected it! I will show two options, one of which is correct.
Both options are similar, but in the second, the lower right leaf is convex and the picture changes, not matching what is shown on the box.
You can also understand that this is not the right option by looking at the edge, which is 3 ml. above, but as I mentioned "the puzzles must match to the millimeter".
Of course, I offered to assemble the puzzle to my young man, he did it much faster, after 15 minutes he showed me the finished figure. "Men... developed logic" I thought, but he did not cope with the second, he did not have enough patience.
I.Q. Puzzle "Rhombus".
This puzzle has 8 pieces. In appearance, everything is simple. I started to collect focusing on the corners. Cunningly! But in the end, I got completely different figures. With this puzzle, the brain had to really break!
After 40 minutes, I left her and proposed to my parents the next day. Father sat for about an hour, proving to me that these details are definitely not from this figure. And all because the semblance of a rhombus turned out, but it was not a solid figure. I'll show you the options.
To be honest, in despair, I tried to find the answer to this puzzle on the Internet, but since it is one of the new products, there were no answers.
The next day I decided to try again and this lesson dragged me on again, but now an hour later the correct option appeared!
I didn’t enjoy this view for a long time, I quickly took everything apart, I didn’t want to remember how to put this or that part correctly, because I planned to try to reproduce it at another time.
And now I'll show you another option, which I came up with a week later. The outlines of a rhombus, but large gaps, which definitely should not be. But I was convinced that this puzzle is not for once.
I brought both puzzles to the company of my friends, the evening at the gathering flew by unnoticed. The tree was assembled quickly, but the rhombus did not submit to them. Friends took turns asking me to take home my puzzles.

Rubik's Pyramid - Science and Life magazine reported on this puzzle in 1982. Then she was a novelty and interest in her was theoretical: "Masha is good, but not ours" as well as children's autotracks. Now the toy factories began to produce a pyramid in large quantities and there was a practical interest: they bought it, but how to assemble it?
There was already a diagram on the site. Recall what was said in the magazine.
The pyramid is a geometric body tetrahedron. Like the Rubik's cube, it consists of elements that, when the faces are rotated, can move from face to face. The role of cubes here is played by small tetrahedra, of which the large tetrahedron is composed. It has four vertices (c), 6 edge elements, or elements at the base (o) and 6 middle elements located between them (m). Around any of the four axes, you can rotate the "apex", or "pyramid" - two tiers at once.
Having placed the tetrahedron with some face towards itself (facade), we denote the vertices in the same way as is customary for the Rubik's cube: B (top), P (right), L (left) and T (back).
The same letters denote turns - clockwise without a stroke, and with a stroke - against. The main movement in solving the puzzle is the rotation of the pyramid, that is, the top, along with the middle layer.
The main operations for bringing the pyramid into order were named: the universal operation of the VLV'L'(PVP'V', PLP'L') type, which cyclically rearranges three elementary pyramids on two faces, and the circular permutation of three elements of one face: П' LPL' clockwise and VL'V'L against. They are enough to solve the puzzle.
Is there an assembly algorithm similar to the algorithm cube assembly Rubik? readers ask.
We give the floor to the inventor of the "Moldavian Pyramid" engineer A. A. Ordynts, who offers two ways to solve the puzzle.
FIRST WAY
Alternate construction of the faces of the pyramid. At the same time, attention is not paid to the destruction of the previously constructed face.
First stage. First of all, all the tops in unfold in their places so that the colors of the sides match the color of the sides of the corresponding middle element, and at the same time diamonds are formed at each vertex on each side vm, consisting of two triangles of the same color. Then the middle elements unfold m
(together with tops in
and edge elements o) so that there are diamonds on each side of the pyramid vm
only one color (see 1.2). Three rhombuses of the same color can only be built on a well-defined face. To facilitate the search for this face, it is necessary to proceed from the fact that the color of this face will be the one that is not on the opposite vertex of this face.
Picture 1
Second phase. After placing one-color diamonds on four faces, for further construction, it is necessary to master auxiliary operations (Fig. 1, 2):
a) transfer of the edge element from the base to the top B without disturbing the construction of rhombuses by the PVP’B’ operation,
b) approach to the initial position of the edge element at vertex B with violation of diamonds at vertex B by operation B or B’.
Third stage. The foundation is being built - the lower layer of the pyramid (Fig. 3a, 36). The dot denotes the side of the edge element, which has the same color as the face under construction located below. The edge element, which has the color of the face under construction, is brought to the initial position with the help of auxiliary operations, while the arrangement of rhombuses at vertex B is allowed. Then, depending on the position of the colors of the sides of this edge element at the initial position, one of the operations For or 3b is applied (TV'T' or L'VL). Triangles of the same color are marked with the same shading in the figures. The color of unshaded triangles does not matter. The result of the stage: the base is built - the bottom layer, in which both on the face facing downwards and on the sides of the base all the triangles are in their places.
Figure 2
Fourth stage. By turning the vertex B, the rhombuses at the vertex B are set in their places, and the pyramid is flipped down with a face of a different color.
Fifth stage. Repeating the third step to build a new face. In this case, one should not pay attention to the fact that the order of the elements on the previously constructed face is violated.
If necessary, the third face is built in the same way. In rare cases, it is necessary to build the fourth face, and the pyramid will be assembled.
SECOND METHOD
Layered construction. After constructing the bottom layer - the base - according to the first method (see the third stage), one of three possible positions will be obtained:
1. Two edge elements at the top are in their places in the expanded position. The rest of the elements are correct. The pyramid is assembled by the process: (P'LPL') (VL'V'L).
Figure 3
2. Three edge elements at the top are out of place. When the vertex is rotated by 120°, they fall into place, however, the vertex and the middle element are incorrectly deployed. In this case, depending on the position, the processes (P’V’P) V’ (P’V’P) or (PVP’) V (PVP’) are applied.
