... A plane angle is the inclination to one another of two lines which meet. When a straight line set upon a straight line makes adjacent angles equal to one another, each of the equal angles is a right angle. Euclid did not define length, distance, inclination, or set upon. Once having made the above d ...

... So how do these facts about rigid motions and symmetry relate to congruence? We define two figures in the plane as congruent if there exists a finite composition of basic rigid motions that maps one figure onto the other. It might seem easy to equate two figures being congruent to having same size s ...
