WebJan 12, 2024 · The interior angles are each 140°. You can verify this because 1260° ÷ 9 (angles) = 140°. The central angle is 40° (which you can calculate by dividing 360° by 9 ). This means you can construct a regular nonagon with 7 isosceles triangles with two angles of 70° and one angle of 40°. Irregular nonagon
What is a Regular Polygon? - Regular Polygons Examples
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 WebFinally, the sum of interior angles is found with the formula 180 (n-2) where n is the number of angles. since it tells us the sum we can find the number of angles. 180 (n-2)=540 n-2 = 3 n = 5 So five corners, which means a … 7 gram rocks crack
