Polygon Interior Angles

This activity is a focus on discovery of interior angle sums of polygons. For additional resources check out my handout here https://tinyurl.com/ybqohnmo CCSS.MATH.CONTENT.8.G.A.5Use informal arguments to establish facts about the angle sum and exterior angle of triangles, about the angles created when parallel lines are cut by a transversal, and the angle-angle criterion for similarity of triangles.  CCSS.MATH.PRACTICE.MP7 Look for and make use of structure.
