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.

1800 degrees (that is the sum of the internal angles of the 12-sided polygon).

Degrees are used to measure angles, not the lengths of sides.

The interior angles of a 12 sided polygon add up to: (12-2)*180 = 1800 degrees

12 sided regular polygon.

Sum of exterior angles = 360 degrees If each one is 12 deg there must be 360/12 = 30 of them. So it is a 30 sided polygon.

Each interior angle in 12-sided polygon is 150 degrees.

If it is a regular 12 sided polygon then each interior angle is 150 degrees.

Degrees are used to measure angles, not the lengths of sides.

The sum of the interior angles of a 12 sided polygon add up to 1800 degrees.

Providing that it is a regular 12 sided polygon then each exterior angle measures 30 degrees

The interior angles of a 12 sided polygon add up to: (12-2)*180 = 1800 degrees

Each exterior angle of a regular 12-gon measures 30 degrees.

The name of a 12 sided polygon is Dodecagon.

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.

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
