Geometer's Sketchpad is an easy-to-use dynamic construction and exploration tool for use in a variety of classes. Using Sketchpad, students discover patterns, formulate conjectures, and verify their conjectures by creating small examples. Students then generalize their justifications to prove a geometric relationship. This paper presents two examples of geometric explorations using Sketchpad.
