It states that the square of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides . The theorem can be written as an equation relating the lengths of the sides a, b and c, often called the "Pythagorean equation": </P> <Dl> <Dd> a 2 + b 2 = c 2, (\ displaystyle a ^ (2) + b ^ (2) = c ^ (2),) </Dd> </Dl>
