In geometry, a tetrakaidecagon (or tetradecagon) is a polygon with 14 sides and angles.The regular tetradecagon is the Petrie polygon for four higher dimensional polytopes. A regular tetradecagon can't be constructed using compass and straightedge. In geometry, a Petrie polygon for a regular polytope of n dimensions is a skew polygon such that every (n-1) consecutive sides (but no n) belong to one of the facets. The Petrie polygon of a regular polygon is the regular polygon itself; that of a regular polyhedron is a skew polygon such that every two consecutive sides (but no three) belong to one of the faces. For every regular polytope there exists an orthogonal projection onto a plane such that one Petrie polygon becomes a regular polygon with the remainder of the projection interior to it. These polygons and projected graphs are useful in visualizing symmetric structure of the higher dimensional regular polytopes.
