A dodecagon is a 12 sided shape that has 12 interior angles that add up to 1800 degrees and 12 exterior angles that add up to 360 degrees
The sum of the interior angles of a 12 sided polygon add up to 1800 degrees.
The total of the interior angles equal 5040, and each angle measures 168 degrees The total of the exterior angles equal 360, and each angle measures 12 degrees
The 3D shape that has 12 faces is called a dodecahedron. It is a polyhedron with 12 regular pentagonal faces. Each face of a dodecahedron is a regular polygon with five sides of equal length and five equal interior angles.
to calculate this, you must find out how many triangles you can draw in to the shape. do this by picking an angle. draw a line to all of the other angles. (for a 12 sided, there would be 9, subtract 3 from any shape to see.) mutiply the number of triangles by 180 degrees. this should be the degrees of the shape. for a 12 sider, the answer would be 1620 degrees.
Assuming it is a two dimensional shape, 12 sides implies 12 angles (interior or exterior).

A dodecagon is a 12 sided shape that has 12 interior angles that add up to 1800 degrees and 12 exterior angles that add up to 360 degrees
The sum of the interior angles of a 12 sided polygon add up to 1800 degrees.
The interior angles of a 12 sided polygon add up to: (12-2)*180 = 1800 degrees
The interior angles add up to 1800 degrees
Exterior angles add up to 360 degrees Interior angles add up to 1800 degrees so all together 2160
