68: The cool pythagorean triangle.

I lied. It's not a Pythagorean triangle. It's TWO Pythagorean triangles that make up a Heronian triangle.
What other Pythagorean Triangle combinations make a triangle like this?

  1. Algebraically, it works for combinations of the bottom two "legs" (a and b) and hypotenuses (e,d) where

    a^2 - b^2 = e^2 - d^2

    i.e. 5^2 - 9^2 = 13^2 - 15^2
