The general formula for the sum in degrees of the interior angles of a regular polygon with n sides is 180(n - 2). The name "dodecagon" means a polygon of 12 sides. Therefore, the sum of the angles is 1800 degrees.

12 The sum of the exterior angles is 360˚. So we have 360/30 = 12 angles which is also the number of the polygon sides.
The interior angles of a 12 sided polygon add up to 1800 degrees

The general formula for the sum in degrees of the interior angles of a regular polygon with n sides is 180(n - 2). The name "dodecagon" means a polygon of 12 sides. Therefore, the sum of the angles is 1800 degrees.

Sum of exterior angles = 360 degrees (whatever the number of sides). So, if the polygon has n sides, 360/n = 12 so that n = 360/12 = 30 sides.
The sum of the interior angles of a polygon is 2n - 4 right angles - where n is the number of sides. So, 1080° = 1080/90 = 12 right angles If 2n - 4 = 12 then 2n = 16 : n = 8 The number of sides is 8.
12 The sum of the exterior angles is 360˚. So we have 360/30 = 12 angles which is also the number of the polygon sides.
The interior angles of a 12 sided polygon add up to 1800 degrees
The formula is: (12-2)*180 = 1800 degrees
12 sides, 12 angles, 12 vertices
The sum of the interior angles of a 12 sided polygon add up to 1800 degrees.
Sum of interior angles of a polygon = (Number of sides - 2)*180 degrees. So, for a polygon, (12 - 2)*180 = 10*180 = 1800 degrees.
A dodecagon
Any polygon can have two interior angles of 12 degrees. No polygon can have all its interior angles of 12 degrees.
