In geometry, a dodecagon, or 12-gon, is any twelve-sided polygon. A regular dodecagon is a figure with sides of the same length and internal angles of the same size. It has twelve lines of reflective symmetry and rotational symmetry of order 12.

In geometry, a 12-sided polygon is called a dodecagon. It also has twelve vertices and twelve interior angles. Let’s take a look at some of the examples of dodecagon in the figure below. Based on the sides and angles, a dodecagon can be classified as a regular or irregular polygon and a convex or concave polygon.
