One of the first college-level texts for elementary courses in non-Euclidean geometry, this volume
is geared toward students familiar with calculus. Topics include the fifth postulate, hyperbolic
plane geometry and trigonometry, and elliptic plane geometry and trigonometry. Extensive
appendixes offer background information on Euclidean geometry, and numerous exercises
