## Definition

The concept `TriangulationFaceBase_2` describes the requirements for the base face class of a triangulation data structure that is itself plugged into a basic triangulation or a Delaunay triangulation.

This concept refines the concept `TriangulationDSFaceBase_2` and could add geometric information. In fact, currently the triangulations do not store any geometric information in the faces and, thus this concept is just equal to `TriangulationDSFaceBase_2` and only provided for symmetry with the vertex case.

Refines:
  `TriangulationDSFaceBase_2`

Has Models:
  `CGAL::Triangulation_face_base_2<Traits>`
