How do you spell the big triangle in the jigsaw puzzle?

The spelling of the jigsaw triangle is as follows:

First, the right angles of the two largest right triangles in the puzzle are overlapped to form an isosceles right triangle. Then, first place the square and find out the two smallest right-angled triangles. The right-angled sides of the smallest right-angled triangle overlap with the two opposite sides of the square to form a small isosceles trapezoid.

Let one side of the parallelogram coincide with the waist of the small isosceles trapezoid to form another large isosceles trapezoid. Then, put the last triangle on the upper bottom of the isosceles trapezoid.

Form a second isosceles right triangle, and overlap the right angles of two large isosceles right triangles.

There are three ways to make a triangle out of a jigsaw puzzle: two large triangles and two small triangles, both of which can be made into squares. Tangram is divided into two triangles, and two different right-angled sides overlap to form a parallelogram. Tangram is divided into two triangles, and two identical right-angled sides overlap to form an isosceles right-angled triangle.

Tangram is an ancient traditional intellectual toy in China. As the name implies, it consists of seven boards. These seven boards can be combined into many figures (1600), such as triangles, parallelograms, irregular polygons, etc. Players can also combine them into various characters, images, animals, bridges, houses, towers, etc., or some Chinese and English letters.
