State curriculum standards are mandating more coverage of geometry, as are the curricula for pre-service mathematics education and in-service teaching. Yet many secondary teachers know just enough geometry to stay one chapter ahead of their students! What's more, most college-level geometry texts don't address their specific needs. 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).
