How to determine the sum of all interior angles of a polygon ex 1

👉 Learn how to determine the sum of interior angles of a polygon. A polygon is a plane shape bounded by a finite chain of straight lines. A regular polygon is a polygon whose sides are congruent (equal). The interior angle of a polygon is the angle between two sides of the polygon. For a regular polygon, the interior angles are congruent (equal). The sum of the interior angles of a regular polygon is given by the formula: 180(n - 2) degrees, where n is the number of sides of the polygon.
