WebMar 21, 2024 · 5.7K views 3 years ago In this clip learn how to calculate the sum of interior angles of a n-gon. To calculate the sum of the interior angles the following formula is used (... 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: Webb) If each interior angle is 157.5˚, then each exterior angle is 180˚!157.5˚=22.5˚. Since the sum of the exterior angles of any n-gon is 360˚, 360˚÷22.5˚! 16sides. Example 4 Find the area of a regular 7-gon with sides of length 5 ft.
