The vertex is the point at which two rays of an angle or two edges of a polygon meet. The plural of vertex is vertices.

A point where two lines or line segments meet or intersect. A triangle has three vertices.

1. The point at which the sides of an angle intersect.

2. The point of a triangle, cone, or pyramid that is opposite to and farthest away from its base.

3. A point of a polyhedron at which three or more of the edges intersect.

The vertex of an http://www.answers.com/topic/angle is the point where two rays begin or meet, where two line segments join or meet, where two lines intersect (cross), or any appropriate combination of rays, segments and lines that result in two straight "sides" meeting at one place.


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.
