a2 + b2 = c2 is use to this triangles because this is the pythagoras thereom. You use this formula whenever something or whenever sides are missing.
(Following pictures contains pictures you won't understand so i recommend a parental advice)
This is how you figure out how a and b fits to the hypotenuse . the next picture is the formula on how to solve the a and b to get c.
Here are the videos of pythagoras thereom
