one simple way to proof Pythagoras' theorem is thatyou can draw a right-angle triangle. a line is 3cm and the
other line is 4 cm. and then you draw the hypotenuse at last.
you then measure it. you will find that it is equal to 5 cm.
so it is the proof. 3x3 +4x4 =5x5

It is only the proof for only one specific case, but not the general proof for the whole case.
