The **floret pentagon** is a type of irregular pentagon with mirror symmetry but no rotational symmetry. It appears as in the vertex figures of several snub polyhedra and thus as faces of their duals.

## Vertex coordinates[edit | edit source]

Coordinates for a floret pentagon with minor edge length 1 and major edge length 2 are:

- ,
- ,
- .

These coordinates lie coincide with vertices of a triangular tiling, and the floret pentagon can be dissected into 7 equilateral triangles.
