Introduction to Non-Euclidean Geometry

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

appear throughout the text.
