The sum of the measures of the exterior angles of a polygon, one at each vertex, is 360°. 3 = > (n − 2) 2 = 3 2 = > n − 2 = 3 = > n = 5 Since x and, ∠ j are remote interior angles in relation to the 120° angle, you can use the formula.

The sum of the measures of the exterior angles of a polygon, one at each vertex, is 360°. Also like with interior angles, the above exterior angles are equal when a transversal line crosses 2 parallel lines. Find the value of an individual angle. Also the value of an exterior angle can be obtained by subtracting the interior angle from 180°.
