What does a dodecagon look like?

Answer 1

You can actually learn to make an origami one. But its a 12 sided figure with each face having 5 sides in my past experience. A dodecagon is a 12-sided polygon, a 2-dimensional figure. The dodecahedron is a 12-sided polyhedron, a 3-dimensional object of 12 pentagonal faces and 20 vertices. The dodecahedron is also one of the Platonic solids.

The above is a totally confused answer. It conflates a a dodecagon and a dodecahedron. The first, which the question is about, is a plane (2-D) figure which is bounded by 12 straight lines. The second, which has nothing to do with the question, is a solid (3-D) shape enclosed by 12 pentagonal faces.
