## Definition

The class `Triangulation_ds_vertex_base_2` can be used as the base vertex for a `Triangulation_data_structure_2`, it is a model of the concept `TriangulationDSVertexBase_2`.

This base class can be used directly or can serve as a base to derive other base classes with some additional attributes (a color for example) tuned for a specific application.

Note that if the `Triangulation_data_structure_2` is used as a parameter of a geometric triangulation, there are additional geometric requirements to be fulfilled by the vertex base class, and `Triangulation_ds_vertex_base_2` cannot be plugged in.

Is Model Of:
  `TriangulationDSVertexBase_2`
