Product Description
This is a brief activity that can be used to help students see and understand the reason why every triangle has 180 degrees. Prior to completing this activity, students should have a knowledge of the angle pairs that are formed when parallel lines are cut by a transversal. Students will manipulate the angles of a triangle in such a way that they are able to see the relationship between angle pairs that are formed and the 180 degrees of the triangle.
