These two triangles are shown to be congruent proving this square has same area left rectangle. In other words nonEuclidean geometry relation between sides of triangle must necessarily take nonPythagorean form. van der Waerden p. When is degrees radians then cos and formula reduces to usual Pythagorean theorem. In any event the proof attributed to him is very simple and called by rearrangement
