How do you find the interior angle of a regular dodecagon?

All sides are the same length (congruent) and allinterior angles are the same size (congruent). To find themeasure of the angles, we know that the sum of all theangles is 1800 degrees (from above) And there are twelveangles So, the measure of the interior angle of a regulardodecagon is 150 degrees.

.

Correspondingly, how do you find the interior angle of a dodecagon?

The measure of an interior angle of a regulardodecagon is 150 degrees. To find this, you need to know theformula for finding the total number of degrees of all theangles of a regular polygon: n-2 (180) where 'n' is thenumber of sides. So, since a dodecagon has 12 sides, n =12.

Secondly, what is the interior angle of a regular 12 sided shape? We can calculate the size of the smaller angle ofthe triangles as all 12 of these angles form a wholecircle (360 degrees). Thus 360 divided by 12 is the size ofthe angle: 30 degrees. The other two angles must addup to 150 degrees, as 180 minus 30 equals 150.

Accordingly, what is the measure of an interior angle of a regular dodecagon?

150°

How do you find the interior angles of a polygon?

A regular polygon is a flat shape whose sides areall equal and whose angles are all equal. The formula forfinding the sum of the measure of the interior anglesis (n - 2) * 180. To find the measure of one interiorangle, we take that formula and divide by the number of sidesn: (n - 2) * 180 / n.
