Problems solved by technology

[0002] At present, there are many kinds of jigsaw puzzles on the market. Most of the jigsaw puzzles are aimed at children, especially young students, and use the development of intelligence to attract their parents to spend money to buy them. However, these puzzles are extremely large. Most of them are jigsaw puzzles made of one scene, one style, and plot fragments in one story with one content and one variety. The content is monotonous, lacks functionality and variability, and can only play a one-time role. Developing the intelligence of young children and cultivating and improving children's innovative ability cannot improve children's creativity and thinking. Over time, the jigsaw puzzles bought back with money will be turned into garbage and discarded. This is a serious social waste, which is not conducive to energy saving and material saving, and is not environmentally friendly

Embodiment Construction

[0026] Such as figure 1 with 2 As shown, in this embodiment, a Pythagorean jigsaw puzzle includes a right-angled triangle plate, a hook edge plate, a stock edge plate and a chord edge plate, and a circular puzzle piece 1 is divided into the right-angled triangle plate.

[0027] Such as image 3 with 4 As shown, the hooking plate is a square plate whose side length is the hooking length of a right-angled triangle plate, and it consists of rectangular pieces a3, b5, square pieces a2, and b4 of different sizes. Assembled, this graphic design is based on the algebraic identity (a+b) 2 =a 2 +2ab+b 2 Completed, the square block a 2 is assembled by four rectangular blocks of equal size and the middle square block c6. This graphic design is based on the algebraic identity (a-b) 2 =(a+b) 2 -4ab completed, the square block c6 is composed of four identical isosceles right triangles.

[0028] Such as Figure 5 with 6 As shown, the stock side plate is a square plate whose side le...

Abstract

The invention discloses a short right-angled side, long right-angled side and hypotenuse jigsaw board, which comprises a right-angled triangle board, a short right-angled side board, a long right-angled side board and a hypotenuse board. The short right-angled side board is a square board, the side length of which is the length of the short right-angled side of the right-angled triangle board. The short right-angled side board is formed by assembling two rectangular joint boards which are equal in size and two square joint boards which are unequal in size. The long right-angled side board is a square board, the side length of which is the length of the long right-angled side of the right-angled triangle board. The long right-angled side board is formed by assembling four right-angled triangle joint boards which are equal in size and a square joint board in the middle. The hypotenuse board is a square board, the side length of which is the length of the hypotenuse of the right-angled triangle board. The hypotenuse board is formed by assembling four right-angled triangle joint boards which are equal in size and a square joint board in the middle. The short right-angled side, long right-angled side and hypotenuse jigsaw board disclosed by the invention is novel in structure and unique in conception and integrates intellectual property, scientificity and enjoyment into a whole; the Pythagorean theorem can be understood intuitively; the creative power and the imagination can be excited; furthermore, the short right-angled side, long right-angled side and hypotenuse jigsaw board is energy-saving, material-saving, green and environment-friendly.
