勾股定理是数学大厦的一块基石,也是数学园地的一株奇葩.在我国据《周髀算经》记载,早在西周开国时期(约公元前1千多年)有个叫商高的人就有论述.国外一般认为这个定理是毕达哥拉斯学派首先最先发现的,因而称为毕达哥拉斯定理.另外在古埃及、古巴比伦、古印度也有有关“勾股定理”的研究.关于“勾股定理”的证明,据说几千年来,人们已经发现了400多种证明方法.
The Pythagorean Theorem is a cornerstone of the mathematics building and a wonderful work of the mathematics garden. In China, according to the records of the Zhouyi calculations, as early as the founding period of the Western Zhou Dynasty (about 1,000 BC), there was a man named Shang Gao. There is an argument. Foreign generally think that this theorem was first discovered by the Pythagorean school, and thus called the Pythagorean theorem. Also in Ancient Egypt, Babylon, and ancient India, there was also the “Pythagorean Theorem.” Research. About the proof of “Pythagorean Theorem”, it is said that over the past thousand years, people have discovered more than 400 kinds of proof methods.
