The method of jigsaw puzzle

The method of jigsaw puzzle is introduced as follows:

1. Tangram is composed of 16 kinds of spelling. Tangram is an ancient traditional intellectual toy in China. As the name implies, it is composed of seven pieces, and these seven pieces can be combined into many figures (more than 1,6 kinds), such as triangles and parallelograms.

2. Rectangle: The two largest triangular pieces are placed in the lower right corner and the lower left corner with a point on the longest side as the contact point, the right angle point of the medium-sized triangular piece is placed down in the middle, and the two right angle sides are next to the longest side of the largest triangular piece respectively, and the remaining small triangular pieces, square triangular pieces and trapezoidal pieces are sequentially spliced on the top from left to right.

3. Square: The two largest triangular pieces are adjacent to each other at right angles to form a large isosceles triangle, and the trapezoid piece and the two smallest triangular pieces are put together in a straight line next to the longest side of the large isosceles triangle, and the remaining medium-sized triangular pieces are put together in the lower left corner.

4. Tangram is put together in different ways, and the combination can be put together into various geometric figures and images, such as bridges, boats, houses, pistols, people running, falling, playing, dancing, standing, fish, cats, dogs and so on.

5. Triangle: the two largest triangular pieces are put together to form a big triangle, and the right angle side is placed on the left side, and the triangular pieces with the same size among the trapezoidal pieces are placed in turn from top to bottom in the middle, and the small triangular piece and the square piece are placed on the rightmost side.
