WebThe sum of all interior angles of a regular octagon is 1080 degrees. Also, each interior angle is 135 degrees. The exterior angle of an octagon measures 45 degrees and the sum of all exterior angles is 360 degrees. … WebAn octagon has 8 sides, so: Exterior angle = 360° / n = 360° / 8 = 45° Interior Angle = 180° − Exterior Angle We know the Exterior angle = 360°/n, so: Interior Angle = 180° − 360°/n Which can be rearranged like this: Interior Angle = 180° − 360°/n = (n × 180° / n) − (2 × 180° / n) = (n−2) × 180°/n So we also have this:
