Create PYthagoreanthereom.py

will help you out with the Pythagorean thereom, if you want to find out a, b, or c...
how it works:
you enter wether you want to find out what 'a' is or what 'c' is
   if you choose 'c' then you input a, and b, it will square those numbers
   then it will add them, then find the square root
if you choose to find a/b then it will as for b and c
   then it will square those nubmers and then it will subtract b from c and that will give you a^2, then it will find the square root of that and then it will tell you the answer
