The Geometer's Sketchpad, Exploring Geometry

Dynamic Geometry® software enriches the study of high school geometry, and its use is recommended in the Common Core State Standards. This collection of Sketchpad activities is aligned to the High School Geometry Common Core State Standards, and covers virtually every concept studied in high school geometry. The activities will help your students visualize geometry concepts, make and test conjectures and justify their conclusions, and deeply explore content related to: - constructing geometric figures - transformations and tessellations - areas of polygons and circles - introductory trigonometry - modeling with mathematics
