勾股定理又称毕达哥拉斯定理,这是一个基本的几何定理,传统上认为是由古希腊的毕达哥拉斯所证明。据说毕达哥拉斯证明了这个定理后,随即斩了百头牛作庆祝,因此又称“百牛定理”。在中国,《周髀算经》记载了勾股定理的一个特例,相传是在商代由商高发现,故又有人称之为商高定理。 The Pythagorean theorem, also known as the Pythagorean Theorem, is a fundamental geometric theorem that was traditionally believed to have been demonstrated by Pythagoras of ancient Greece. It is said that Pythagoras proved this theorem, then cut a hundred cows for celebration, it is also called “Bull’s Theorem ”.
