How To Find The Measure Of One Interior Angle. By the Triangle Exterior-Angle Theorem an exterior angle of a triangle measures the sum of its remote interior angles. For both methods we will use the fact that the sum of the measures of the interior angles of a.
Additionally if we have a regular polygon ie all sides and angles are equal then we can find the measure of each interior angle by dividing the sum of the interior angles by the number of sides. In this case n is the number of sides the polygon has. The formula for finding the sum of the measure of the interior angles is n - 2 180.
Youll learn how to do this with the steps outlined in.
Properties of Interior Angles. Enter the number of sides in the input field. The sum of interior angles of a regular polygon and irregular polygon examples is given below. The formula for finding the sum of the measure of the interior angles is n - 2 180.
