How to put together a tangram into a square, use 6 pieces of tangram to make a square

Tangram is an ancient traditional Chinese intellectual toy, as the name suggests, it is composed of seven boards, which can form a variety of graphics, today I will take you to see how to use tangram to spell out a square.

1.Put one piece of the big triangle into the square box, and put the other part of the big triangle into the square box.

2.Two triangular plates make up half of the square and also form a large triangle.

3.The middle triangle is placed in the empty corner of the box, and the remaining five plates form the other half of the large triangle.

4.Drop the small triangle and then the small square to form a trapezoid.

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

1. Give the tangram.

Nos: No. 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 of our ancestors. At the beginning of the 19th century, the tangram spread to the West and was known as the "Oriental Magic Board".

There are seven types of arrangement.

1. Use two identical triangles to form a square.

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

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

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

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

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

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

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).

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 puzzles to make a square. Tools Raw material: Tangram.

1. The first step is to prepare a pair of tangrams, marked with numbers on them, so that everyone can learn from them.

2. In the second step, take the chop and bring out the No. 2 to put it in a good position, as shown in the figure below.

3. In the third step, take out No. 1 and put it on top of No. 2, as shown in the figure below.

4. In the fourth step, take out No. 4 and put it next to No. 2, as shown in the following fierce picture.

5. In the fifth step, take out No. 5 and put it on top of No. 4, as shown in the figure below.

6. In the sixth step, take out No. 6 and put it on top of No. 5, as shown in the figure below.

7. In the seventh step, take out No. 3 and place it next to No. 6, as shown in the figure below.

8. In the eighth step, finally take out No. 7 and put it next to No. 5 and No. 3, and put the square together.

Tangram is made up of two large triangles, a medium triangle, two small triangles, a square and a parallelogram, and the method of putting together a square is as follows:

1. First, take a large square, place it at a right angle, take another big triangle at a right angle and place it to the right, and place a small triangle on the top right of the first big triangle, at a right angle to the left.

2. Place a square below the small triangle, one side of the square is aligned with one side of the small triangle, take another small triangle, the right angle is wide upward, and one side is close to the square.

3. Place the parallelogram below the second small triangle and place the medium triangle in the lower right corner, so that the square is spelled out.

Expansion: Tangram is an ancient Chinese traditional intellectual toy, which is composed of seven boards, which can be spelled into many graphics, and can also be spelled into various characters, images, animals, bridges, houses, towers, etc., and can also be spelled into Chinese and English letters.

Tangram is made up of five isosceles right triangles (two small triangles, one medium triangle, and two large triangles), one square, and one parallelogram, and the complete pattern is a square. The benefits and uses of tangram are: training shape concepts, visual discrimination, intellectual skills, visual memory, hand-eye cooperation to encourage openness, diffusion thinking, creative machine encounters, etc.
