Students use Sketchpad to develop a proof for a result that was discovered and used (without proof) in an earlier activity. The link to the tool itself is to a zip file that contains both the sketch and a pdf file of the corresponding activity.
This is a free sample activity from Rethinking Proof with the Geometer's Sketchpad.
