Abstract:
The proportion angle of a non-square rectangle R, written ‘Pa (R)’, is defined to be the angle r 〈 between a diagonal and the longer attached side. Circumscribe around R any other rectangle M that carries the corners of R on its sides, and let its proportion angle be m , which is also 〈 . Then the theorem states that r 〈 m .
