You can put this solution on YOUR website!
The Distance Formula, using points (h,k) and (p,r):
sqrt%28%28h-p%29%5E2%2B%28k-r%29%5E2%29

The diagonals in your graph are the point pairs (-b,c) and (a,0);
and (b,c) and (-a,0).

Substitute into the formula to make the expression for each diagonal. These are
sqrt%28%28-b-a%29%5E2%2B%28c-0%29%5E2%29 and sqrt%28%28b-%28-a%29%29%5E2%2B%28c-0%29%5E2%29.
Simplify these. (BASIC ALGEBRA SKILLS)
