How to make a square with a jigsaw puzzle?
How to spell a square with a puzzle is as follows:

Method 1:

1, Tangram consists of the following seven boards, and the complete pattern is a square: five isosceles right triangles (two small triangles, one middle triangle and two large triangles), a square and a parallelogram.

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

3. Rectangular, the two largest triangular pieces are placed in the lower right corner and the lower left corner respectively, with the point on the longest side as the contact point, the right-angle point of the medium-sized triangular piece is placed in the middle, and the two right-angle sides are respectively next to the longest side of the largest triangular piece, and the remaining small triangular pieces, square triangular pieces and trapezoidal pieces are spliced on the topmost side from left to right.

4. Triangle: the two largest triangular pieces are put together to form a big triangle, with the right-angled side on the left, the trapezoidal piece and the medium-sized triangular piece in the middle from top to bottom, and the small triangular piece and the square piece on the right. This is a puzzle of educational toys.

2, forming according to the figure, that is, discharging the answer from the known figure; Instant typesetting: find out one or more typesetting methods from known graphics; Creating your own graphics can create new ways of playing and arranging; Mathematical research, using jigsaw puzzles to solve or prove mathematical problems.

3. Tangram can be assembled into various geometric figures and images according to different methods, such as bridges, boats, houses, pistols, people running, falling, playing, dancing, standing, fish, cats, dogs and so on.
