Sum of angles in a 12 sided polygon
WebAll sides are the same length (congruent) and all interior angles are the same size (congruent). To find the measure of the angles, we know that the sum of all the angles is 1800 degrees (from above)... And there are twelve angles... So, the measure of the interior angle of a regular dodecagon is 150 degrees. WebThe sum of an interior angle and the exterior angle of one side of a polygon is equal to 180° since both the angles lie in a straight line. If there are 3 sides in a polygon, then on each …
