WebNov 13, 2024 · $\begingroup$ Any regular polygon has its exterior angles in arithmetic progression (with difference $0$). Do you consider that a valid case? If ... b=10$ with external angles $10°, 20°, 30°, \cdots 80°$ in Arithmetic Progression. Remark 1: A discussion should take place about the sidelengths of the polygon, for which there is a ... WebAs you can see, for regular polygons all the exterior angles are the same, and like all polygons they add to 360° (see note below). So each exterior angle is 360 divided by the n, the number of sides. As a demonstration of this, drag any vertex towards the center of the polygon. You will see that the angles combine to a full 360° circle. chinese food in springdale ar
