 Methods of Geometry Wiley, 2000

This text for the junior or senior level geometry survey course offered by many mathematics departments is distinguished by these features:

 * A thorough but concise survey of elementary Euclidean geometry--in the spirit of Moïse's Elementary Geometry from an Advanced Standpoint--intended to get everyone started at the same place. * Inclusion of classical "advanced" Euclidean geometry of triangles and circles, including most of plane and spherical trigonometry. * Emphasis on the classification of isometries in 2 and 3 dimensions--only Martin's book is equally thorough. * A chapter on symmetry groups, including classification of frieze and wallpaper groups comparable to Martin's, and a discussion of the structure, classification, and symmetries of polyhedra. * A large collection of non-routine exercises, quite a few of which require considerable computation. For solutions, click here. * Ample attention to the history and philosophy of geometry.
