Irregular Polygons To find the measurement of an exterior angle, simply take the corresponding interior angle and subtract it from 180. Since the interior and exterior angle together add up to a straight line, their values should equal 180 degrees.
To find the measure of exterior angle corresponding to x° in the above polygon, first we have to find the value of x. The above diagram is an irregular polygon of 6 sides (Hexagon) with one of the interior angles as right angle. Formula to find the sum of interior angles of a n-sided polygon is. = (n – 2) ⋅ 180°.
