It is generally considered that the Greece mathematician, Pythagoras, first proved the Pythagorean theorem, but this is not reliable.

在西方，一般都认为：希腊数学家半达哥拉斯（Pythagoras）最早证明了勾股定理，因而都习惯地称这个定理为毕达哥拉斯定理。但这一看法历史上并没有可靠的依据。

Even if admit this view, in the western countries the time of first proof of the Pythagoras theorem is not probably early than epoch ago 585 year.

The Pythagorean Theorem tells us that a3-4-5 triangle is a right triangle, so we can simply test for sides of3,4, and5.

勾股定理（Pythagorean Theorem）告诉我们边长为3、4和5的三角形是直角三角形，因此可以使用边长3、4和5来简单地测试。

For instance, it's also the square of the Euclidean norm on R2, the length of a two-dimensional vector, a part of the triangle inequality, and quite a bit more.

例如，R2的平方、二维向量的长度、三角不等式等都存在勾股定理。
