Building on the prior knowledge about interior angles of polygons, this lesson will show students the relationship between the interior and exterior angles of a polygon. Using visual demonstrations students will deduce that the sum of exterior angles in a polygon will add up to 360 degrees. Students can then use this knowledge to complete a wide range of problems involving interior/exterior angles in polygons.
