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.

The triangle is one of the most fundamental shapes in geometry, and many mathematical principles are built on its properties. Among these, the Triangle Sum Theorem stands as a cornerstone, establishing that the sum of the interior angles of any triangle is always equal to 180 degrees. This theorem is not only a basic fact to memorize but also an essential building block that enables more advanced geometric reasoning.
