Sum of exterior angle of a polygon
Web13 Oct 2024 · This video is about showing that the sum of exterior angles of any polygon is 360 degrees. WebHexagon has 6, so we take 540+180=720. A heptagon has 7 sides, so we take the hexagon's sum of interior angles and add 180 to it getting us, 720+180=900 degrees. Same thing for an octagon, we take the 900 from before and add another 180, (or …
Sum of exterior angle of a polygon
Did you know?
Exterior angles of a polygon are the angles formed between one of the sides of the polygon and outward extension of the adjacent side. The sum of all the exterior angles of a polygon is 360 degrees. We will prove this statement in the following sections and look at some examples. See more The word polygon comes from the Greek word poly, meaning many, and gon, meaning angle.
