Web3 May 2024 · A rule of polygons is that the sum of the exterior angles always equals 360 degrees. There are six sides in a hexagon, or n = 6. ∴ Exterior angle θ = 360 n = 360 6 = 60∘. Answer link.

WebA regular hexagon has six sides. The interior angle is 120° and the exterior angle is 60°. A regular octagon has eight sides. The interior angle is 135° and the exterior angle is 45°. Web22 Dec 2024 · The sum of the angles of an octagon is 1080°. The sum of the interior angles of a polygon with n number of sides is always (n − 2) × 180°. Thus, an octagon's angles add up to (8 − 2) × 180° = 1080°.

Web8 Aug 2024 · Thus, for regular octagons, n = 8, so each interior angle is 180 × 6 8 = 135 o, and thus each exterior angle is 180 o − 135 o = 45 o. The sum of the angles of an n -gon is 180 ( n − 2). Plugging n = 8 here, we obtain 180 × 6 = 1080 ∘. Since the polygon is regular, an interior angle measures 1080 8 = 135 ∘.
