How do you find the exterior angle of a shape
WebJul 9, 2024 · An exterior angle has its vertex where two rays share an endpoint outside a circle. The sides of the angle are those two rays. The measure of an exterior angle is found by dividing the difference between the measures of the intercepted arcs by two. Example: Find the measure of angle EXT, given that the exterior angle cuts off arcs of 20 degrees ...
