WebWe get. So, the sum of the interior angles of an 11-gon is 1620 degrees. Regular 11-gons: The properties of regular 11-gons: All sides are the same length (congruent) and all interior angles are the same size (congruent). To find the measure of the angles, we know that the sum of all the angles is 1620 degrees (from above)... WebInterior Angle = Sum of the interior angles of a polygon / n. Where “n” is the number of polygon sides. Interior Angles Theorem. Below is the proof for the polygon interior angle sum theorem. Statement: In a polygon of ‘n’ sides, the sum of the interior angles is equal to (2n – 4) × 90°. To prove:
