Math
If you are referring to the Pythagorean Theorem, it is that a2+b2=c2. A and B are the two shorter sides and C is the hypotenuse. This formula applies to any right-angled triangle, where you have the known length of two sides, and want to find the length of the third side.
My favorite math subject is Trigonometry Algebra!
