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: WebIn geometry, an icosagon or 20-gon is a twenty-sided polygon. The sum of any icosagon's interior angles is 3240 degrees. Regular icosagon ... One interior angle in a regular icosagon is 162°, meaning that one exterior angle would be 18°. The area of a regular icosagon with edge length t is = ...
