## What’s a 12 sided polygon?

**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 with all sides the same length is a regular polygon known as a regular dodecagon.**

## What is a 10 sided polygon called?

decagon

## What does decagon meaning?

Definition of decagon : **a plane polygon of 10 angles and 10 sides.**

## Is a decagon a regular polygon?

A decagon is a 10-sided polygon, with 10 interior angles, and 10 vertices which is where the sides meet. A regular decagon has 10 equal-length sides and equal-measure interior angles. Each angle measures 144xb0 and they all add up to 1,440xb0 . An irregular decagon has sides and angles that are not all equal or congruent.

## What is 12 sided polygon called?

A 12 sided shape is a polygon called **a dodecagon. Basically, a dodecagon is a polygon made up of 12 sides, 12 angles, and 12 vertices. The name of this 12-sided shape comes from the Greek words ‘dodeka’ and ‘hedra’, that mean ‘twelve’ and ‘seat/base’.**

## How many sides does a 12 sided polygon have?

A 12 sided shape is a polygon called a dodecagon. Basically, a dodecagon is a polygon made up of 12 sides, 12 angles, and 12 vertices.

## What is a 12 sided prism called?

The **decagonal prism has 12 faces, 30 edges, and 20 vertices, so, it is a dodecahedron (while the term is usually applied to regular dodecahedron or rhombic dodecahedron.).**

## What is 10 sided called?

In geometry, **a decagon (from the Greek u03b4u03adu03bau03b1 dxe9ka and u03b3u03c9u03bdu03afu03b1 gonxeda, x26quot;ten anglesx26quot;) is a ten-sided polygon or 10-gon. The total sum of the interior angles of a simple decagon is 1440xb0. A self-intersecting regular decagon is known as a decagram.**

## What is a decagon shape?

A decagon can be defined as **a polygon having ten sides, ten interior angles and ten vertices.**

## What is the root word for decagon?

The word decagon comes from Greek roots, **deka, or x26quot;ten,x26quot; and gu014dnia, x26quot;angle or corner.x26quot; Any ten-sided shape can be called a decagon, whether it’s a street sign or the doodle you draw in your notebook during math class.**

## Is a decagon regular or irregular?

Types of Decagons: Decagons can be categorized as **regular and irregular. A regular decagon is a decagon with all sides equal in length and all the angles equal in measure. In a regular decagon, the interior angles add up to 1440 degrees, and the exterior angles add up to 360 degrees.**

## What are the properties of a regular decagon?

A regular decagon is a polygon along with10 equal sides and 10 vertices. The sides and angles are congruent in a regular decagon. The characteristics of a regular decagon are: **All sides are equal in length and all the angles are equal in the measure in a regular decagon**
