We use these relationships to derive the general formula for polygonal numbers. In finding the number of dots in a polygon, two quantities vary. The first varying quantity is the number of sides of the polygon which we have denoted above as n. The second quantity is the size of the polygon which we denote as k.
Best Answer: Nonagon is a nine-sided ploynomial. the formula for the sum of all the interior angles of a regular polygon is: (n - 2) * 180 (in degrees) (9-2) * 180 = 1260 degrees. As an aside, this mean that each interior angle in a regular nonagon = 1260/9 = 140.
