Dodecagon - Wikipedia
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.

A dodecagon is a closed figure that has 12 sides and 12 angles. It has 12 vertices, each of which is connected to two sides. See the below figure which is an example of a dodecagon.
What Is Dodecagon? Definition, Types, Area, Properties, Examples
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.
Dodecagon - Definition, Formula, Properties, Types, Examples
A dodecagon is a polygon with 12 sides, 12 angles, and 12 vertices. Dodecagons can be of different types depending upon the measure of their sides, angles, and many such properties. A regular dodecagon has all 12 sides of equal length and all angles of equal measure. An irregular dodecagon has sides and angles of different measures.

A dodecagon is a 12-sided two-dimensional plane figure. The term dodecagon is derived from Greek, where "dodeka" indicates 12 (do = two, deka = 10) and gon means angle or corner. The figure below shows some dodecagon examples:

Properties of dodecagons, interior angles of dodecagons. Using the same methods as for hexagons to the right (I'll let you do the pictures)... To find the sum of the interior angles of a dodecagon, divide it up into triangles... There are ten triangles... Because the sum of the angles of each triangle is 180 degrees... We get.
