How do I calculate the exterior angle of a decagon? To determine the exterior angle of a regular decagon: Recall the formula for the sum of interior angles: n× 180° - 360°, where n is the number of sides. In our case n = 10, so 10 × 180° - 360° = 1440°. There are ...
a closed plane figure bounded by three or more straight sides that meet in pairs in the same number of vertices, and do not intersect other than at these vertices. The sum of the interior angles is (n--2) × 180° for n sides; the sum of the exterior angles is 360°. A regular ...
