Find the sum of the interior angles of a nonagon

First, determine the number of sides. Count

The formula for calculating the sum of the interior angles of a regular polygon is: (n - 2) × 180° where n is the number of sides of the polygon. Given "n = 14#. #:. " Sum of the interior angles of a 14-gon polygon is. (n −2) ⋅ 180 = (14 − 2) ⋅ 180 = 2160∘. Answer link. color (green) (2160^@ The formula for calculating the sum of ...A nonagon can have 6 diagonals drawn inside of it to form 7 interior triangles. Every triangle's angles have a sum of 180˚. Therefore, since there are 7 triangles, the sum of the interior angles in a nine-sided polygon is. 7 × 180˚ = 1260˚. This can be generalized to a polygon with n sides, since n − 2 triangles can be drawn in any polygon.
