Sum Of Interior Angles And Exterior Angles Of A Polygon. Exterior Angle of Regular Polygons. Exterior Angles Sum of Polygons.
The sum of an interior angle and its corresponding exterior angle is always 180 degrees since they lie on the same straight line. The angle formed by any side of a polygon and the extension of its adjacent side is known as Exterior angle. A regular polygon has sides of equal length and all its interior and exterior angles are of same measure.
Here is the formula.
In any polygon the sum of an interior angle and its corresponding exterior angle is. Click the checkboxes next to the drawing to make the interior or exterior angles. Exterior Angle of Regular Polygons. The sum of the internal angle and the external angle on the same vertex is 180.
