Transformation Geometry: An Introduction to Symmetry offers a modern approach to Euclidean Geometry. This study of the automorphism groups of the plane and space gives the classical concrete examples that serve as a meaningful preparation for the standard undergraduate course in abstract algebra. Th[...]
"The Foundations of Geometry and the Non-Euclidean Plane" is a self-contained text for junior, senior, and first-year graduate courses. Historical material is interwoven with a rigorous ruler - and protractor axiomatic development of the Euclidean and hyperbolic planes. Additional topics include the[...]
