This resource provides six videos describing angles and similar triangles and two videos to check for understanding. Topics covered include: angle definition, degrees in a circle, straight angles, supplementary & complementary angles, opposite angles, and two parallel lines cut by a transversal. The Angle Game is a review video that begins with a figure created by intersecting lines, providing the measure of two angles and challenges students to find the measure of another angle. The resource continues with videos about similar triangles, applying what was learned previously to find the measures of the angles of the triangles. An Angle Game is used again to reinforce the ideas explained in the similar triangle videos by asking students to find the measure of an angle in a star shaped figure when the measure of three other angles are given. The videos are all easy to follow and are mathematically sound providing a great resource for the classroom. Most of the videos are close to ten minutes in length.

This is truly a very helpful and easy to understand source. The lessons which are seemingly not too long and to the point; cover all the topics in the chapter…

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 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.
