An octagon consists of 8 interior angles and 8 exterior angles. The sum of the interior angles of an octagon is 1080°, and the sum of its exterior angles is 360°. There are 20 diagonals in an octagon. Octagons are classified into various types based upon their sides and angles.

Web13 jun. 2024 · A pentagon is a 5-sided shape. Angles in pentagons always add up to 540°. To find a missing angle in a pentagon, add up the 4 known angles and subtract this from 540°. We first add the 4 known angles: 120° + 100 + 100 + 110° = 430°. We then subtract this from 540°: 540 – 430 = 110 and so the missing angle is 110°. opening a gift shop in trinidad and tobago
