[pstricks] Right triangle to scale

[David Arnold]

All,

Is there a cute way to present an algorithm a pythagorean triple and  
have a right triangle drawn to scale in a space that measures 2 inches  
by two inches?

For example, I feed the problem 3, 4, 5 and I get a right triangle  
with sides 3, 4, and 5.

Thanks.

David.
