勾股定理揭示了直角三角形三边之间的关系,其逆定理则是判定三角形是直角三角形的一种方法,怎样运用这两个定理呢?本文介绍几种思路。一、已知图形中有直角三角形时,可考虑运用勾股定理
The Pythagorean theorem reveals the relationship between the three sides of a right-angled triangle. The inverse theorem is a way to determine whether a triangle is a right-angled triangle. How do we use these two theorems? This article introduces several ideas. First, consider the use of Pythagorean theorem when there are right-angled triangles in the known graphics
