Angles of a Triangle Scavenger Hunt This is a group/partner activity in which students use what they have learned about properties of triangles and angles and theorems such as the triangle sum theorem to find missing angles of a triangle, and when given an expression for an angle, to find the variable that makes the description of the triangle true. This activity is structured to promote positive interdependence and push students to make sense of the problems and persevere in solving them.
