Exterior angle triangle formula

WebHere, S = sum of interior angles and n = number of sides of the polygon. Applying this formula on a triangle, we get: S = (n − 2) × 180°. S = (3 − 2) × 180°. S = 1 × 180°. S = 180°. Using the same formula, the sum of the interior angles of polygons are calculated as follows: Polygon. Number of sides, n. WebThe Formula. As the picture above shows, the formula for remote and interior angles states that the measure of a an exterior angle ∠ A equals the sum of the remote interior angles. To rephrase it, the angle 'outside the triangle' (exterior angle A) equals D + C (the sum of the remote interior angles).
