Find The Sum Of The Measures Of The Interior Angles Of Each Convex Polygon. 14-gon. 18 -gon 628721 An 18 -gon has eighteen sides. The sum of the interior angle of a 10-sided polygon is _______ If each interior angle of a regular polygon measures 140 how many side does the polygon have.
20 -gon 628721 A 20. Sum of the interior angles of a 14-gon polygon is n-2 180 14 -2 180 2160. The rule is that a polygon with n sides has a sum on interior angles given by 180circn-2.
Where n is the number of sides of the polygon.
