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 …

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.

A dodecagon is a polygon with 12 sides, 12 angles and 12 vertices. It can be regular, irregular, concave, or convex, depending on its properties.

The word dodecagon comes from a Greek word that implies twelve angles. Explore the different types of dodecagons and their properties with solved examples.

A dodecagon is a polygon with twelve sides as well as twelve vertices and twelve internal angles. This fact is encoded in the word itself, as dodeka is Greek for twelve.

Dec 22, 2025 · A dodecagon is a 12-sided polygon. Several special types of dodecagons are illustrated above. In particular, a dodecagon with vertices equally spaced around a circle and …

What Is Dodecagon? A dodecagon is a polygon (closed, flat figure) with 12 straight sides and 12 angles. It can be regular (all sides and angles are equal) or irregular (sides/angles can differ). …

A dodecagon is a twelve-sided polygon. It is one of the most commonly studied shapes in geometry and is used in a variety of applications. Understanding the properties of this shape …

A dodecagon is a 12-sided polygon with 12 vertices and interior angles. Explore its types, including regular and irregular forms, and learn how to calculate area and perimeter through …

To find the exterior angle of a regular dodecagon, we use the fact that the exterior angle forms a linear pair with the interior angle, so in general it is given by the formula 180-interior angle. …
