Interior Angles, Exterior Angles, and Diagonals of Polygons
8th - 11th CCSS: Adaptable
How does the number of sides of a polygon affect the angle measures? Learners recognize a pattern in finding the total measure of interior and exterior angles and the number of diagonals. They use the patterns to calculate the number of...
How Do You Find the Sum of the Interior Angles of a Polygon?
6 mins 6th - 10th
Squares, pentagons, triangles, polygons. How is it possible to figure out the sum of the interior angles of any of these multi-faceted shapes? There's got to be a formula. Of course there's a formula. That's what algebra is all about,...
The Sum of the Interior Angles of a Polygon
4th - 5th CCSS: Adaptable
Junior geometers discover that polygons can be decomposed into triangles and that the number of triangles can be determined by a rule. Note that the Geometer’s Sketchpad® software is required to carry out all components of this activity.
