Best Answer

The top of a cone, seen from the outside of the cone, is called the vertex, also referred to as the externalpoint.

The vertex is the point of intersection of the lines, or generators, of the cone and the plane base, in this case a circle. But if you just call it the point, everyone will know what you mean.

This is referring to what we all think of when we hear the term, cone: a right circular cone. There are other types of cone, but probably not of interest here.

A cone does not have a vertex. A vertex is defined as a point where two lines meet; a triangle has three vertices, and the angular face of a pyramid has a vertex. However, a cone is a three-dimensional figure and has a curved surface. The base of a cone is circular. The top of the cone is a single point called the apex of the cone.
