The Pythagoras Theorem states that, in any right-angled triangle, the sum of the squares of the two smaller sides of the triangle equals the sum of the square of the hypotenuse
It can be algebraically expressed as a squared plus b squared equals c squared where a, b are lengths of the smaller sides and c is the length of the hypotenuse
The converse of the Pythagoras Theorem states that for any three positive numbers a, b and c which satisfy the relation a squared plus b squared equals c squared, there exists a right triangle with the right angle between the sides of the lengths a and b
