Angles in a Polygon

Activity Overview

Students will expore the interior and exterior angle of 3 polygons and develop the formula to calculate the sum of degrees without the measurement of the angles being taken.

Before the Activity

download the following files for measurement polygon1 polygon2 polygon3 These files will be needed on each students calculator. You will need to load them using the TI Navigator or the black link cables

During the Activity

Use student instruction and worksheet.

After the Activity

Discussion of the formula that have been developed will provide additional information on angles and polygon. This discussion should include information about regular polygons and how to find individual angle measures in the regular polygons
