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.
Can you illustrate how the sum of all angles of a triangle is 180 degrees. Learn the concept of basic geomtery in a fun way.
