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 ° By using the formula, sum of the interior angles of the above polygon is = (6 - 2) ⋅ 180 ° = 4 ⋅ 180 ° = 72 0 ° -----(1)

- The formula to find the sum of the interior angles of any polygon is sum of angles = (n - 2)180°, where n is the number of sides of the polygon. The sum of exterior angles of any polygon is 360º. Read the lesson on angles of a polygon for more information and examples.
- Interior and Exterior Angles in Polygons — Practice Geometry Questions By Allen Ma, Amber Kuang In geometry, you can find the sum of the interior or exterior angles of a polygon based on the number of sides the polygon has. You can then apply this information to find individual interior or exterior angles.
Here is what we know about exterior angles and polygons: 1. A polygon with n sides will have n interior angles and n exterior angles (one at each vertex). 2. By its formation, an exterior angle is supplementary to its adjacent interior angle. 3. At each vertex of the polygon, the interior angle and the exterior angle form a linear pair.
