# It's a right triangle again!

Geometry Level 4

A Pythagorean triangle is a right triangle in which all three sides are integer lengths. Let $$a, b$$ be the legs of a Pythagorean triangle, and $$h$$ be the altitude to the hypotenuse.

How many non-congruent triangles are there such that $$\large \frac {1}{a} +\frac{1}{b} +\frac{1}{h}=1$$.
