WebA heptagon is a polygon with 7 sides and 7 angles. Sometimes the heptagon is also known as “septagon”. All the sides of a heptagon meet with each other end to end to form a … WebAnswer (1 of 8): Decagon is a polygon which has 10 sides. The sum of its interior angles is 1440 degrees. And by the formula to find the sum of interior angles we have:- Sum of interior angles = 180(n-2) Where 'n' is the number of sides of any polygon. Therefore 1440=180(n-2) 1440/180=n-2 8+2=n ... divisibility by prime strong induction
