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 ... WebDec 6, 2024 · According to this theorem, in a convex polygon, the sum of all the exterior angles is equal to 360°. This can be proved in the following way; We know that sum of interior angles of a polygon is given by 180° × (n-2) where n is the number of sides of the polygon. So, the measure of each interior angle of the polygon will be 180° × (n-2) / n. cs141 default password
