|Activity: Exterior Angles in a Polygon|
|Go to:||http://www.keypress.com/.../ExteriorAngles.zip (opens a new window)|
Students construct a pentagon with its exterior angles, measure the angles and find the sum. They then dilate the pentagon to look at the problem, and understand their result, in a new way. The link to the activity itself is to a zip file that contains a pdf file of the activity.
This is a free sample activity from Exploring Geometry with the Geometer's Sketchpad.
