WebJul 20, 2024 · The circle bounding the disk represents 360 ∘ . One arc of the circle is interior to the polygon, one arc exterior. The boundary of the polygon splits the disk into inside and outside. The total interior arc length is the internal angle; the total exterior arc length is the exterior angle: Internal + external = 360 ∘ : 90 ∘ + 270 ∘ and ... 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."
