In geometry and trigonometry, an angle (in full, plane angle) is the figure formed by two rays sharing a common endpoint, called the vertex or vertex of the angle (vertices in plural).

With solid figures, like pyramids or polyhedrons, a vertex is a corner where three or more of the faces meet.

Remember,

* faces are the flat sides.

* Edges are the lines where two of the faces meet.

* Vertices are the corners where three or more of the faces meet.
