Solution

## The correct option is A $$360^o$$An exterior (or external) angle is the angle between one side of a triangle and the extension of an adjacent side.An exterior angle of a triangle is equal to the sum of the opposite interior angles. If the equivalent angle is taken at each vertex, the exterior angles always add to $$360$$ degrees.Mathematics
