Books by H.S.M. Coxeter

In Euclidean geometry, constructions are made with ruler and compass. In projective geometry one never measures anything, instead, one relates one set of points to another by a projectivity. The concluding chapters show the connections among projective, Euclidean, and analytic geometry.

This textbook introduces non-Euclidean geometry, and the third edition adds a new chapter, including a description of the two families of 'mid-lines' between two given lines and an elementary derivation of the basic formulae of spherical trigonometry and hyperbolic trigonometry, and other new material.
