|Activity: Proof as Verification: Areas|
|Go to:||http://www.keypress.com/.../Areas.zip (opens a new window)|
Students form a conjecture about the ratio of two areas in a quadrilateral, and use Sketchpad to search for a proof. In the process they verify or disprove their results for two different kinds of quadrilaterals. The link to the activity itself is to a zip file that contains both the activity in pdf format and the corresponding sketch.
This is a free sample activity from Rethinking Proof with the Geometer's Sketchpad.
