Procedure calculates the longest side , or hypotenuse , of a right triangle , given the values for the other two sides
过程通过给定的直角三角形的两条直角边计算该三角形的最长边（即斜边）。
He proved the pythagorean theorem : in a right triangle , the square of the hypotenuse is equal to the sum of the squares of the other two sides
毕达哥拉斯证明了勾股定理，就是指在直角三角形中，两条直角边的平方和等于斜边的平方。
Construct a right triangle with given hypotenuse c such that the median drawn to the hypotenuse is the geometric mean of the two legs of the triangle
这题大概是：构造一个直角三角形（斜边c已给定），使斜边上的中线长度是两直角边长度的比例中项。
