To calculate this, you must find out how many triangles you can draw into the shape. Do this by taking the total number of sides (s) and taking away 2. This leaves you with how many triangles you can draw in the shape (t) from one vertex to another. (Not including outside lines!). Then, multiply the number of triangles in the shape by 180. This leaves you with how many degrees are inside that shape. (a)

t = s-2
a = t X 180

This means there are 1800 degrees in a 12 sided polygon.

### What is the interior angle of a 12- sided shape?

The total interior angle of a 12 sided polygon is = (12 - 2) 180 degrees = 1800 degrees. The internal angle at each vertex of an regular dodecagon is equal to = = 150 degrees. While the exterior angle at a single vertex is = = 30 degrees. The total exterior angle of a 12 sided polygon is 360 degrees.

### How many sides does a polygon have if one of the interior angles is 30 degrees?

No such regular polygon exist so it has to be some kind of irregular polygon but if each exterior angle was 30 degrees then it would be a regular 12 sided polygon
