Pythagoras showed how right-angled triangles can be made up of triplets of whole numbers, such that "the square on the hypotenuse is equal to the sum of the squares on the other two sides". Fermat alleged that he had proved that this is ONLY true of square numbers. Other sets of three numbers, be they cubed, or to the power 4, etc etc, NEVER conform to the same rule / relationship. The above picture / graphic explains the famous Fermat's Last Theorem. Square - Composition | Horizontal | Explaining | UK | Right Angle
