What is the sum of the interior angles of a nonagon?
The formula is (n-2)180
Number of sides in a nonagon is 9. The formula for the sum of the interior angles of a polygon is: 180(n-2), where n is the number of sides. 180(9-2) 180*7 1260°
N stands for the number of sides, there are 9 sides
Sum of interior angles of a polygon = (n-2) × 180° in this equation, substitute n with 9, to get the sum for a nonagon.
