G Pythagorean Theorem Quiz 1
Contributed by: Cason
Always ask do I have both legs of a right triangle.If so, we add to get the hypotenuse.  
Use a2 + b2 = cand then find the square root of cor   a2 + b2 =   c by taking the square root first.
Or do we have a hypotenuse and one leg?  Then we need to subtract.
Use c2 - a2 = b2   and then find the square root of b2  or   c2 - a2  =  b by taking the square root first.
