These free geometry worksheets will introduce you to the Triangle Sum Theorem, as you find the measurements of the interior angles of a triangle. The interior, or inside, angles of a triangle always add up to 180 degrees. In addition to your geometry skills, you'll be able to polish your algebra skills as you set up and solve equations on some of the tougher triangles. 4 1 worksheet triangle sum and exterior angle theorem Levels of Difficulty : Elementary Intermediate Advanced That is what we know from the triangular theorem, that the sum of all angles must be 180 degrees; thus if we begin with 55, the remainder is 125 In any polygon, the sum of an interior angle and its corresponding exterior angle is 180.
