勾股定理是直角三角形的一个重要性质 ,这个定理被发现至今已有五千多年历史了 .在我国公元前一百多年就记载了勾股定理的应用 .在欧洲通常被称为毕达哥拉斯定理 ,传说毕达哥拉斯为首的学派首先在理论上证明了勾股定理 .据说为庆贺定理的证明 ,他们杀了 10 0头牛祭神 .由此可见 The Pythagorean theorem is an important property of right-angled triangles. This theorem has been discovered for more than 5,000 years. The application of the Pythagorean theorem was documented in more than one hundred years BC. It is commonly referred to as Pytha in Europe. The Golath theorem, the legendary Pythagorean school of thought, first proved the Pythagorean theorem in theory. It is said that in order to prove the proof of the theorem, they killed 100 cattle cult gods.
