Web11 Jan 2024 · The interior angles of a dodecagon are a bit harder. You can use this generic formula to find the sum of the interior angles for an n -sided polygon (regular or irregular): Sum of interior angles = (n-2)\times 180° (n − 2) × 180° Sum of interior angles = 10\times 180°=1800° 10 × 180° = 1800° Web6 Feb 2024 · Sum of Interior angles of an undecagon = (2×11-4)×90° = (22-4)×90° = 18×90 = 1620° Hence, the sum of the interior angles of an undecagon is 1620° Find Math textbook …
WebThe sum of the interior angles of a dodecagon can be calculated with the help of the formula: (n - 2 ) × 180° = (12 – 2) × 180° = 1800°. Exterior Angles of a Dodecagon Each exterior angle of a regular dodecagon is equal to 30°. If we observe the figure given above, we can see that the exterior angle and interior angle form a straight angle (180°). WebAs you can see, for regular polygons all the exterior angles are the same, and like all polygons they add to 360° (see note below). So each exterior angle is 360 divided by the n, the number of sides. As a demonstration of this, drag any vertex towards the center of the polygon. You will see that the angles combine to a full 360° circle.
