An exterior angle is 360/n, where n is the number of sides in a polygon. For 12 sides, this is 30 degrees.
An easy way to see this is by the matchstick test, a visualization exercise. Start with a regular polygon and a matchstick. Place the matchstick, head first, on one of the sides. Slide it in the direction of the head, turning it as necessary to fit each side.
After you've moved it around the figure, it has rotated exactly once for 360 degrees. On a 12-sided figure it turned 12 times, so 360/12 was the amount of each turn.
For those who can't visualize a matchstick easily, you can use a pencil and it's eraser end.
it has twelve sides
A Dodecagon. (In geometry, a dodecagon is a polygon with exactly twelve sides. When spelled uppercase, the outlines of the letters E and H (and I in a slab serif font) are all dodecagons.
Three dimensional shapes with faces are called polygons. They are named using prefixes derived from Latin, so a 12 sided polygon is named a dodecagon, where dodeca- means twelve.
Well, twelve inches make up one foot, and 1/3 yards make up a foot, is that what you were asking for?
the answer to it is 12,13,212
If the 12-sided polygon is 'regular', then each of its exterior angles is 30 degrees. Whether the polygon is regular or not, all 12 of its exterior angles still add up to 360 degrees, but they may not all be equal.

A polyhedron with twelve regular pentagons as sides is called a dodecahedron.

A dodecagon is a polygon that has twelve sides. A regular dodecagon has twelve internal angles of 150 degrees each.
Central is an adjective, not a noun. So the question depends on central what? And since you have not bothered to provide that crucial bit of information, I cannot provide a more useful answer.
A twelve sided polygon is called a dodecagon.
A twelve sided polygon is called a dodecahedron. No, that is a twelve faced solid (3-D) object. A 12 sided polygon is a dodecagon.
Exterior angles add up to 360 degrees Interior angles add up to 1800 degrees
It will have 12 sides
