Students work in pairs or groups of three to determine the missing angle measures in two figures that are composed of interlocking triangles. Students must be able to apply the Linear Pair Postulate, Vertical Angle Theorem, Triangle Sum Theorem, and Exterior Angle Theorem in order to determine the measures of the missing angles.
Students create posters to display their results, including explanation of the process used to determine the measures of two specific angles. This is intended to be
