Polygon exterior angle theorem

WebThe sum of the internal angle and the external angle on the same vertex is π radians (180°). The sum of all the internal angles of a simple polygon is π ( n −2) radians or 180 ( n –2) … WebNov 16, 2013 · What this means is just that the polygon cannot have angles that point in. If a polygon does have an angle that points in, it is called concave, and this theorem does not apply. In other words, all of the interior angles of the polygon must have a measure of no more than 180° for this theorem to work."
