The **tetradecagon** is a polygon with 14 sides. A regular tetradecagon has equal sides and equal angles.

It has two non-compound stellations, these being the tetradecagram and the great tetradecagram.

It is the uniform truncation of the heptagon.

## Vertex coordinates[edit | edit source]

Coordinates for a regular tetradecagon of edge length 2sin(π/14), centered at the origin, are:

- (±1, 0),
- (±cos(π/7), ±sin(π/7)),
- (±cos(2π/7), ±sin(2π/7)),
- (±cos(3π/7), ±sin(3π/7)).

## Stellations[edit | edit source]

- Stellated tetradecagon
*(compound of 2 heptagons)* - Tetradecagram
- Stellated tetradecagram
*(compound of 2 heptagrams)* - Great tetradecagram
- Stellated great tetradecagram
*(compound of 2 great heptagrams)*
