(9 − 2) × 180 ∘ = 7 × 180 ∘ = 1260 ∘ “Equiangular” tells us every angle is equal. So, each angle is 1260 …

Given that each interior angle of a regular polygon is seven times …

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 WebOctagons have 8 sides so again, we need to adjust the formula accordingly: sum of internal angles = (8 - 2) x 180°. 1080° = 6 x 180°.
