Advanced Euclidean Geometry fills this void by providing a thorough review of the essentials of the high school geometry course and then expanding those concepts to advanced Euclidean geometry, to give teachers more confidence in guiding student explorations and questions. The text contains hundreds of illustrations created in The Geometer's Sketchpad Dynamic Geometry? software, and it is packaged with a CD-ROM (for Windows?/Macintosh? formats) containing over 100 interactive sketches using Sketchpad(TM) (assumes that the user has access to the program).
