1. The problem statement, all variables and given/known data[/b](adsbygoogle = window.adsbygoogle || []).push({});

3. if X m and n are positive rational numbers, X(m^2 ~ n^2) , 2Xmn , and X(m^2+n^2) are positive rational numbers. Hence show how to determine any number of right-angle triangles the lengths of all whose sides are rational

2. Relevant equations

3. The attempt at a solution

What does the tilde mean in this context, he doesnt explain use it anywhere else or explain what it is. Also what does "determine any number of right-angle triangles..." mean? Is it asking you to find a general expresion for the lengths of the sides of a triangle whose sides are rational?

-Thanks
