Find The Number Of Sides Of Polygon From Sum Of Interior Angles Youtube Text exterior angle of a polygon 360 div text number of sides Remember the interior and exterior angle add up to 180. . The name tells you how many sides the shape has. For example if the exterior angle is 60 degrees then dividing 360 by 60 equals 6 which is the number of sides the polygon has. That yields an interior angle of 180 - 133333333 which equals 166666666667 or 166 and 23 degrees. The sum of any triacontagons interior angles is 5040 degrees. Most have five or more. A polygon with 27 sides will yield an exterior angle of 360 27 133333333 or 13 and 13 degrees. S 180 n 2 where n is the number of sides If the sum is 900 we have.
