How do you spell a square with a tangram? Use 6 tangram puzzles to form a square

Tangram Square Method Steps:1. Put one piece of the big triangle into the square box, and then put the other piece of the big triangle into the square box.

2. Two triangles form half of the square, and also form a large triangle.

3. Put the middle triangle plate into the empty corner of the square box, and the other five plates form another large triangle that spits and changes the crime and a half.

4. Put down the small triangle, then put down the small square, and form a ladder into a single book.

5. Put down another small triangle, and finally put down the parallelogram to form another trapezoid.

Tangram is an ancient traditional Chinese intellectual toy, as the name suggests, it is made up of seven boards that can form a variety of graphics.

Use tangram puzzles to spell squares, start with one corner of the square, put together the largest figure first, and then spell the small shape, so that the easiest, the following will spell the square together.

01 Prepare a set of tangrams, which you can make yourself with paper, which is both cost-effective and fun. There are three kinds of triangles in the tangram: large, medium and small, which are called large, medium and small respectively.

02 Place a large triangle flat on the table as the bottom edge of the square.

03 Place the second large triangle on the top right of the first large triangle, which is the second side of the square.

04 Place the parallelogram to the left of the first large triangle.

05 Place a small triangle on the top right of the parallelogram.

06 Place the square on the top right of the small triangle.

07 Place the second small triangle on the top right of the square.

08 Finally, place the medium triangle on the top left of all the shapes, and the square is finished.

6 jigsaw puzzles can't make a square. Whether it is 6 pieces in a set of tangrams, or 6 sets of 42 pieces in a set of tangrams, it is impossible to spell out a square.

With 6 pieces can only spell out a rectangle:

A square with a side length of 1 cm and an area of 1 square centimeter; A square with a side length of 1 decimeter and an area of 1 square decimeter; A square with a side length of 1 meter and an area of 1 square meter; A square with a side length of 1 km has an area of 1 square kilometre.

1 square kilometer (km) = 100 hectares (ha) = acre (acre) = square mile (mile).

1 square meter (m) = square foot (ft).

1 acre (are) = 100 square meters (m).

1. There are seven ways to arrange a tangram square

1. Use two identical triangles to form a square.

2. Use two identical small triangles to form a square.

3. Use a large triangle and two small triangles of the same size to form a square.

4. Use a large triangle and two small triangles and squares of the same size to form a square.

5. A large triangle and two small triangles of the same size and a parallelogram are put together to form a square.

6. Use a large triangle and a medium triangle and two small triangles of the same size to form a square.

7. The seven shapes are all put together into squares.

Second, how to spell seven square pieces of tangram.

1. Tangram is composed of two large triangles, a medium triangle, two small triangles, a square and a parallelogram.

2. Take a large square and place it at a right angle.

3. Take another piece of large triangle at a right angle and place it to the right.

4. Place a small triangle on the top right of the first large triangle, at a right angle to the left.

5. Place a square below the small triangle, and one side of the square is aligned with one side of the small triangle.

6. Take another small triangle, right angle upward, one side close to the square.

7. Place the parallelogram below the second small triangle.

8. Place the medium-sized triangle in the lower right corner.

There are 8 ways to put a tangram into a square as follows:

1.Two large triangles.

2.Two small triangles.

3.One medium triangle and two small triangles.

4.One large triangle and two small triangles and a square.

5.One large triangle and two small triangles and one parallelogram.

6.One large triangle and one medium triangle and two small triangles.

7.One medium triangle, two small triangles, one parallelogram, one square.

8. A pair of tangram can be spelled into a large square.

Which two figures in a tangram can be put together to form a square:

The tangram has seven figures, in which there is a square, a parallelogram, two large square angles of the same size and two small triangles of the same size, and a triangle that is not too big and not too small.

Two of the same large triangles can be put together into a square, and two small triangles can also be put together into a square. (Because the right-angled sides of a regular triangle are equal, and the two acute angles are 45 degrees, you can get a square with all four sides equal and an angle of 90 degrees.) )

Tangram, also known as wisdom board and tangram, is a kind of intellectual toy in ancient China. A tangram is made up of seven plates, the complete pattern is a square, containing: five isosceles right triangles (two small triangles, one medium triangle and two large triangles), one square and one parallelogram.

Tangram is a good partner for inspiring children's intelligence in late chaos, which can connect children with the bridge between objects and forms, cultivate children's observation and imagination, and have a huge space for shape analysis and creative logic.

Tangram can also teach children to recognize colors, guide children to understand the segmentation and synthesis of shapes, and then enhance children's hands-on ability, patience and observation.

There are several ways to put a tangram into a square

1. The tangram is composed of seven plates below, and the complete pattern is a square: five isosceles right triangles (two small triangles, one medium triangle and two large triangles), one square and one parallelogram.

2. Square, put the largest two triangle pieces at right angles next to each other to form a large isosceles triangle, trapezoidal pieces and the two smallest triangle pieces are put together in a straight line on the longest side of the large isosceles triangle, and the remaining medium-sized triangle pieces are put together in the lower left corner.

3. Rectangle, the two largest triangular pieces are placed in the lower right corner and the lower left corner respectively with the longest side of a point as the contact point, the right-angle point of the medium-sized triangular piece is placed downwards in the middle, the two right-angled edges are next to the longest side of the largest triangular piece respectively, and the remaining small triangular pieces are squared and small triangular pieces and trapezoidal pieces are put together on the top side in turn from left to right.

4. Triangle, the two largest triangle pieces are put together into a large triangle with a right-angle side and placed on the left, and the trapezoidal piece is placed in turn from top to bottom in the middle Medium-sized triangle piece, and the rightmost piece is placed with a small triangle piece and a square piece, and the puzzle toy tangram - skillfully spelled shape.

Two. 1. As a traditional toy, the complete shape of the tangram is a square. It can be spelled into various figures, animals, plants, buildings, letters and other graphics.

There are many ways to spell tangrams, and the ways to spell tangrams increase as you continue to get creative. Feel free to spell out the graphics you design.

In general, the figure assembled with tangram should be composed of all seven boards, and there should be connections between the boards, such as the connection of points, the connection of lines, or the connection of points and lines; It can be played by one person or by several people at the same time.

2. Forming according to the diagram, that is, the answer is discharged from the known figure; See the shadow pattern, find one or more types of arrangement from the known figure; Create your own graphics, you can create new ways to play and arrange by yourself; The study of mathematics, the use of tangrams, to solve or prove mathematical problems.

3. Tangrams can be assembled and combined into a variety of geometric figures and images according to different methods, such as bridges, boats, houses, pistols, or running, falling, playing, dancing, standing figures, and fish, cats, dogs, etc.

Tangram one.

01 First of all, after making sure that the number of tangram puzzles is correct, we first find the two largest triangles, and then place them on both sides of the tangram in turn to complete the first step.

02 After placing the two large triangles, we find a medium-sized triangle and the only square in the seven puzzles, and place the triangle opposite the two large triangles we have placed, and the square is placed in the middle of the three triangles (as shown in the picture).

04 In the last step, I found the only parallelogram in the puzzle and placed it in the space required by the tangram and I was done! Is it very simple, friends, hurry up and try it.

1. Number the tangrams: 1-7.

2. Use No. 3, No. 5, and No. 7 triangle tangram puzzles to form a square.

At the same time, the combination of No. 1 and No. 2 tangrams, No. 3 and No. 5 tangrams, can also be put together into squares.

Tangram is a remarkable creation that I envy my ancestors. At the beginning of the 19th century, the tangram spread to the West and was known as the "Oriental Magic Board".
