In mathematics, the Pythagorean theorem — or Pythagoras' theorem — is the relation in Euclidean geometry among the three sides of a right triangle (right-angled triangle). In terms of areas, it states:

In any right-angled triangle, the area of the square whose side is the hypotenuse (the side opposite the right angle) is equal to the sum of the areas of the squares whose sides are the two legs (the two sides that meet at a right angle).

In the above equation: C = The Hypotenuse of a right triangle A & B = Lengths of the other two sides.
