How many angles does a polygon have? - Answers
WebJan 16, 2024 · The minimum number of triangles created in our hexagon, by drawing three diagonals, is four; each triangle has interior angles adding to 180°, so the sum of the interior angles of a regular hexagon is 4 × 180°, or 720°. Regular polygon formula The formula for calculating the sum of interior angles of any regular polygon with n sides is: WebJun 13, 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°.
