...having a circular base, and its other extremity terminating in a single point called its apex or vertex. It may be conceived to be generated by the revolution of a right-angled triangle about one of its sides containing the right angle, which is fixed, and is called the axis of the cone. It is sometimes... | |

A right circular cone is often called a cone of revolution, because it can be generated by the revolution of a right-angled triangle about one of its shorter sides.
