The triangle sum theorem, also known as the triangle angle sum theorem or angle sum theorem, is a mathematical statement about the three interior angles of a triangle. \({\text{65 }} + {\text{ 4}}0{\text{ }} + {\text{ }}\left( { - {\text{8 }} + {\text{ 83}}} \right){\text{ }} = {\text{ 18}}0\), \({\text{65 }} + {\text{ 4}}0{\text{ }} + {\text{ 75 }} = {\text{ 18}}0\), \({\text{18}}0{\text{ }} = {\text{ 18}}0\) . The Triangle Sum Theorem says that the three interior angles of any triangle add up to \(180^{\circ}\). Plug it and compute the measure of the indicated angle in Part A and the measure of four angles in Part B. 1. 2) 124. You can choose between interior and exterior angles, as well as an algebraic expression for the unknown angle. It also helps them build equations, because the interior angles of a triangle always add up to 180 degrees. /Pages 3 0 R Subtract the sum of the two angles from 180 to find the measure of the indicated interior angle in each triangle. /F12 12 0 R example. Plug in x = 11 into all the angles to find their measures. They mainly involve finding out the value of specified unknown angles of a triangle.
