Yes, the sum of the exterior angles of a triangle is always equal to 360°. See Interior/Exterior angle relationship in a polygon. The word comes from the Greek words for “ten” (“deka”) and for “angle” or “corner” (“gonia”). The sum total of these angles is always equal to 360°. The exterior angle of a polygon is the angle formed by one side of the polygon and the extension (or continuation) of the adjacent side. The root word hexa means six, indicating the hexagon’s characteristic six sides, which sets it apart from other polygons. If we extend one of the sides of a polygon, the angle between the extended side and the side next to it is called an exterior angle. While there are other conventions for naming p A circle is not a polygon because it does not conform to the definition of a polygon. For a formal proof the only way I can think of at the moment is to use the fact that the interior angle sum is $180(n-2)$. This works in either direction. The exterior angle theorem states that when a triangle's side is extended, the resultant exterior angle formed is equal to the sum of the measures of the two opposite interior angles of the triangle.
