# What Is a 12-Sided Polygon Called?

**A 12-sided two-dimensional polygon is called a dodecagon.** A regular dodecagon has 12 sides that are all the exact same length and internal angles that are 150 degrees each. Since there are 12 internal angles, the total internal angles add up to 1,800 degrees.
