TABLE OF CONTENTS

This video defines angles, shows several examples of angles, and teaches some simple rules for analyzing them using the degrees of a circle, a straight line, and perpendicular lines.

This video reviews the rules from the introduction to angles video and introduces new types of supplementary and complementary. It also defines the rule for opposite angles.

This video defines parallel lines and explains to rules for angles made when parallel lines are intersected by a transversal. It also teaches how to solve for the 3rd interior angle of a triangle when 2 angles are known.

This video uses tools from mathwarehouse.com to further explain the rules for analyzing the angles formed when parallel lines are intersected by a transversal.

This video uses the rules learned in previous videos in order to analyze angles in a given figure.

This video introduces the concept of similar triangles and explains the rules needed to solve for their angles and sides.

This video picks up where the Similar Triangles Part 1 video left off and continues to explain the rules used for solving angles and sides of similar triangles.

This video gives more practice on solving angles using the information given for a particular figure.
