Refer to the figure above. Finding the measures of an interior angle and an exterior angle of a regular polygon: An exterior angle is an angle formed outside the polygon’s enclosure by one of its sides and the extension of its adjacent side. This means we can divide 360 360 360 360 by 8 8 8 8 to get the solution.
