As I implemented the tests for equilateral and isoscelestriangles, I realized that I was using only the delta value for calculations in right triangles.
当实现对等边三角形和等腰三角形的测试时，我认识到我只用了delta值来用于直角三角形的计算。

In this paper it is proved that there exist neither right triangles nor isoscelestriangles with integer sides and medians by the method of descending.
本文用逐步递降法的思想证明了不存在边长和中线都是整数的直角三角形和等腰三角形。
