Exterior angles of a regular polygon
WebExterior angle is 40 degree. Interior angle = 140. Hence, the number of sides in the polygon is 9. 140 = (n-2) × 180 n 140n = (n -2) × 180 140n = 180n-360 360 = 180n … WebWe can see that all the exterior angles of a polygon have a total sum of 360°. Therefore, we can calculate the measure of one of the exterior angles of a regular polygon by …
Exterior angles of a regular polygon
Did you know?
WebSince all interior angles in a regular polygon are equal, we can say that the interior angle of polygon = sum of interior angles ÷ number of sides. Now, we know that sum of exterior angles of a regular polygon is 360 °. The formula to calculate the measure of an exterior angle is: exterior angle of polygon = 360 ° ÷ number of sides = 360 ° /n.
WebSum of interior angles = (n – 2) ∙ 180°. 1.
