State Pythagoras theorem.

Pythagoras Theorem states that, in a right angle triangle, the square of the hypotenuse equals to the sum of the squares of its remaining two sides. Thus, in a right ∆ ABC , in which ∠ C = 90 ° . We have: AB 2 = BC 2 + AC 2 If, AB = c , BC = a and AC = b , then we have : c 2 = a 2 + b 2
