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 WebWhat is the sum of the measures of the interior angles 150 To find the total amount of degrees in any shape we can use formula: (n-2)* 180 [Where n = number of sides] (12-2)* 180 (10)* 180 =1800

The Sum of The Interior Angles of an N-gon Theorem Proof
WebJun 5, 2024 · So you can find the size of the exterior angles of a regular polygon quite easily: If there are 18 sides (n = 18), then each exterior angle is: 360° n = 360° 18 = 20°. The sum of the exterior and interior angles is 180° because they are adjacent angles on a straight line. ∴ each interior angle is 180° − 20° = 160°. Answer link.
