Polygon theorem
WebNov 28, 2024 · The Exterior Angle Sum Theorem states that the exterior angles of any polygon will always add up to 360 ∘. Figure 4.18.3. m∠1 + m∠2 + m∠3 = 360 ∘. m∠4 + m∠5 + m∠6 = 360 ∘. The Exterior Angle Theorem states that an exterior angle of a triangle is equal to the sum of its remote interior angles. Web6 years ago. So if we know that a pentagon adds up to 540 degrees, we can figure out how many degrees any sided polygon adds up to. Hexagon has 6, so we take 540+180=720. A …

WebDec 6, 2024 · According to this theorem, in a convex polygon, the sum of all the exterior angles is equal to 360°. This can be proved in the following way; We know that sum of interior angles of a polygon is given by 180° × (n-2) where n is the number of sides of the polygon. So, the measure of each interior angle of the polygon will be 180° × (n-2) / n.
