Find The Measure Of Each Exterior Angle Of A Triangle. An exterior angle of a triangle is equal to the sum of the opposite interior angles. As you can see from the picture below if you add up all of the angles in.
This may be one the most well known mathematical rules- The sum of all 3 interior angles in a triangle is 180. A2 b2 72 242 625 c. F 86 8 Q P G 35 95.
9 R H 8 6 x 4x 2 30 Q P 12-1-.

Remember that the two non-adjacent interior angles opposite the exterior angle are sometimes referred to as remote interior angles. Lets say we have the triangle below and were trying to find x the measure of the exterior angle.
