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.
