A dodecagon is a 2-dimensional polygon with twelve edges. The Bowers acronym for a dodecagon is dog.

Structure and Sections

The regular dodecagon has each angle at 150 degrees. It can be seen as a truncated hexagon.

Hypervolumes

  • vertex count = $ 12 $
  • edge length = $ 12l $
  • surface area = $ 3\left(2 + \sqrt{3}\right) l^2 $
