Solution
Anexterior angleof a polygon is an angle that forms a linear pair with one of the angles of the polygon.
Two exterior angles can be formed at each vertex of a polygon. The exterior angle is formed by one side of the polygon and the extension of the adjacent side. For the hexagon shown at the left, <1 and <2 are exterior angles for that vertex. The sum of the exterior angles is always equal to 360∘.
