Related introduction:

The Pythagorean theorem is a basic geometric theorem, which means that the sum of the squares of the two right-angled sides of a right triangle is equal to the square of the hypotenuse. In ancient China, the right triangle was called Pythagorean, and the smaller of the right-angled sides was the hook, the other long right-angled side was the strand, and the hypotenuse was the chord. Therefore, this theorem was called the Pythagorean theorem, and some people also called it the Shanggao theorem.

There are about 500 ways to prove the Pythagorean Theorem, which is one of the theorems with the most proof methods among mathematical theorems. The Pythagorean Theorem is one of the important mathematical theorems discovered and proved by mankind in the early days. It is one of the most important tools for solving geometric problems using algebraic thinking, and it is also one of the links between numbers and shapes.

In China, Shang Gao during the Zhou Dynasty proposed a special case of the Pythagorean theorem of "hook three strands, four strings and five". In the West, the first person to propose and prove this theorem was the Pythagoreans in ancient Greece in the 6th century BC. He used deduction to prove that the square of the hypotenuse of a right triangle is equal to the sum of the squares of the two right-angled sides.
