Exterior angles of a polygon are formed with its one side and by extending its adjacent side at the vertex. Learn in detail angle sum theorem for exterior angles and solved examples.
The Exterior Angles of a Polygon add up to 360°In other words the exterior angles add up to one full revolution.Press Play button to see.(Exercise: try this with a square, then with some interesting polygon you invent yourself.)Note: This rule only works for simple polygons....
