Provides a review of the essentials of high school geometry and then expands those concepts to advanced Euclidean geometry, to give teachers more confidence in guiding student explorations and questions. This text is packaged with a CD-ROM containing over 100 interactive sketches using Sketchpad.

"Advanced Euclidean Geometry" provides a thorough review of the essentials of high school geometry and then expands 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. It is packaged with a CD-ROM containing over 100 interactive sketches using Sketchpad! (assumes that the user has access to the program).
