Tetradecagon

A tetradecagon or tetrakaidecagon is a polygon with 14 sides and 14 vertices.

Regular Tetradecagon

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

Angles of the Tetradecagon

The sum of interior angles of a tetradecagon = (14 − 2) · 180° = 2,160°

The value of an interior angle of a regular tetradecagon is: 2,160º : 14 = 154.29º

The central angle of a regular tetradecagon measures: 360º : 14 = 25.71º

Diagonals of the Tetradecagon

The number of diagonals in a regular tetradecagon = 14 · (14 − 3) : 2 = 77

Perimeter of a Regular Tetradecagon

Perimeter = 14 · l
