WebJan 11, 2016 · As each triangle has 180°, you can find the sum of the interior angles of the polygon: For an n -sided polygon there are (n −2) triangles. The sum of the interior angles is therefore 180°(n −2) In a 15 -sided polygon: Sum interior angles = 180(15 − 2) = 180 × 13 = 2340° Each interior angle of the regular polygon = 2340° 15 = 156° Answer link WebJan 31, 2024 · A diagonal is any line segment drawn between vertices of a polygon that doesn’t include the sides of that polygon.
