Investigating the Angle-Sum Theorem of Polygons
Activity Overview
This activity will allow students to use Cabri Jr. to find the sum of the measures of interior angles of convex polygons and visually see how the Interior Angle Sum Theorem works.
Before the Activity
Give student copy of activity. Students should have some prior knowledge of Cabri Jr.
During the Activity
Students to use Cabri Jr. to find the sum of the measures of interior angles of convex polygons and visually see how the Interior Angle Sum Theorem works.
After the Activity
Discuss with students their finding and answer any questions that the sudent have. Reteach concepts as necessary.
