This activity guides students to develop rules for the properties of exterior angles of a triangle. Through inquiry-based learning, students are able to discover the theorem on their own and therefore understand the concept better and can remember why it works.
This is a coloring activity for a set of 12 problems on the exterior angle sum theorem. The exterior angle is equal to the sum of the two remote interior angles. Problems 1 - 6 are easy and problems 7 - 12 are challenging where algebra is reinforced.
This is a maze of 11 triangles with an exterior angle that students must use the Exterior Angle Theorem and their ability to set up & solve equations to solve for x. This self-checking activity helps students strengthen their skills in solving equations involving the exterior angle theorem.Important InformationNot all boxes are used in the maze to prevent students from just guessing the correct route.
