Sum of the exterior angles of a polygon (video) Khan …

WebJun 15, 2024 · First we need to find the sum of the interior angles; set n = 9. (9 − 2) × 180 ∘ = 7 × 180 ∘ = 1260 ∘ “Equiangular” tells us every angle is equal. So, each angle is 1260 ∘ 9 = 140 ∘. Example 5.27.5 An interior angle in a regular polygon is 135 ∘. How many sides does this polygon have? Solution WebPolygons. A polygon is closed plane figure formed by the joining of three or more straight lines. A regular polygon is one that has equal sides and equal interior angles. n-gons, so a 23 sided polygon would be called a 23-gon. The sum of the measures of the angles of a convex polygon with n sides is (n - 2)180. WebThere are 180 (N – 2) degrees in a polygon if we add up the measures of every interior angle: Sum of Interior Angles of an N-gon = 180 (N – 2) degrees. For example, a polygon with N = 22 sides has 180 (22 – 2) = 180 (20) = 3600 degrees. That is, the sum of all interior angles in a 22-sided polygon is 3600 degrees. 7g is how many tablespoons
