Tetradecagon

The tetradecagon, or ted, 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
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

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