In this online math worksheet, students find the interior and exterior angles of polygons. This excellent resource allows the students to check their answers, and to get "hints" should they run into difficulties. A terrific teaching tool!

In this geometry worksheet, learners identify the interior and exterior angles using the angle sum theorem. They identify and solve quadrilaterals using properties of quadrilaterals. There are 12 questions with an answer key.

This tutorial with video and slideshow components investigate the characteristics of polygons as well as how to calculate the interior and exterior angles of any polygon. It offers two PowerPoint presentations and two videos that feature...
