180 degrees
.
Moreover, how do you work out the interior angle of a 12 sided polygon?
As the angles are identical we can calculate them by dividing 150 by 2: 75 degrees. As the interior angle of the shape is made of two of these angles we can calculate it by doubling the size of the angle. 75 times 2 equals 150 degrees. This is the size of the interior angle.
Subsequently, question is, what is the sum of the interior angles of a polygon with 14 sides? Since all angles of a regular polygon are congruent, the sum of the interior angle measures is 14x. By the Polygon Interior Angles Sum Theorem, the sum of the interior angle measures can also be expressed as . The measure of each interior angle of a regular polygon with 14 sides is about 154.3.
