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.
This is a hands on activity on the Triangle Angle Sum Theorem. Students will cut out 5 triangles and color the 3 angles of each triangle. Students will glue their triangle on top of an identical triangle then fold the 3 angles to create a straight line. This helps students see why the sum of the angles in a triangle su
