Pythagoras Theorem also known as Pythagorean theorem is related to Euclidean geometry among the three sides a(Adjacent side), b(Opposite side), and c(Hypotenuse side) of the right angled triangle. In a right angled triangle, the square of the hypotenuse is equal to the sum of the squares of the adjacent and opposite sides. This formula depicts the pythagoras or pythagorean theorem.
