Triangle Angle Sum Theorem Problems

Angle Sum Property and Exterior Angle Theorem | Triangle Worksheets

This is a great way to review the Triangle Sum Theorem. Students look at different triangles and calculate the missing angle in each. They do not need protractors and should use subtraction and addition. This is a great way to review and works wonderfully as a filler activity. There are three sets of worksheets and answer keys are included.
