WebThe measure of each interior angle of n-sided regular polygon = [ (n – 2) × 180°]/n The measure of each exterior angle of an n-sided regular polygon = 360°/n Area and Perimeter Formulas The area and perimeter of different polygons are based on the sides. Area: Area is defined as the region covered by a polygon in a two-dimensional plane. WebIn Euclidean geometry, a regular polygon is a polygon that is direct equiangular (all angles are equal in measure) and equilateral (all sides have the same length). Regular polygons may be either convex, star or skew.

WebMar 25, 2016 · The perimeter of a regular polygon with n sides of side length s is P = n s. Since. s 2 = r sin ( θ 2) and. θ 2 = 1 2 ⋅ 2 π n = π n. we have. s 2 = r sin ( π n) s = 2 r sin ( π n) Hence, the perimeter of the regular polygon is. P = n s = n [ 2 r sin ( π n)] = 2 n r sin ( π n) WebDec 11, 2024 · This is true for any polygon with n sides, regular or not, and it follows from the fact that an n -sided polygon can be divided into ( n − 2) triangles, and the sum of the measures of the interior angles of each of those ( n − 2) triangles is 180 degrees. Second, we observe that the angle measure of a complete trip around any point is 360 degrees.

But because a polygon can’t have a negative number of sides, n must be 15. So you have a 15-sided polygon (a pentadecagon, in case you’re curious). cthulhu ghostbustersWebSince the number of sides of a polygon cannot be negative, we discard the n = -10 solution. Therefore, the regular polygon with 65 diagonals has 13 sides (n = 13).
