|Tool: Proof as Explanation: Distances in an Equilateral Triangle||
|Go to:||http://www.keypress.com/.../Distances.zip (opens a new window)|
Students explore the sum of certain distances in an equilateral triangle, and develop a proof to explain their observations. 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.
