Calculating lengths and angles in shapes
WebIn a regular octagon, all the sides are equal in length, and all the angles are equal in measure. The interior angles add up to 1080° and the exterior angles add up to 360°. The interior angle at each vertex of a regular octagon is 135°. Irregular Octagon. An octagon in which the sides and angles are not congruent is an irregular octagon.

WebApr 7, 2024 · We know that the formula for calculating the sum of a polygon's inner angles is (n – 2) 180°. As a result, each interior angle = {(n – 2) 180°}/n. Each exterior angle is known to be supplementary to the inner angle. Thus, each outside angle = {180°n -180°n + 360°}/n = 360°/n may be calculated using the preceding method.
