Vertex

A vertex (Latin: whirl, whirlpool; plural vertices), in geometry, is a corner of a polygon (where two sides meet) or of a polyhedron (where three or more faces and an equal number of edges meet).

In 3D computer graphics, a vertex is a point in 3D space with a particular location, usually given in terms of its x, y, and z coordinates. It is one of the fundamental structures in polygonal modelling: two vertices, taken together, define the endpoints of a line; three vertices define a planar triangle.

In graph theory, a graph describes a set of connections between objects. Each object is called a vertex or node. The connections themselves are called edges or arcs.
