A [[conic section]] is the two dimensional curve that is the intersection of a plane with a right circular [[cone]]. In mathematics, a cone extends to infinity, and goes in both directions from its apex.

A '''conic section''' is the two dimensional curve that is the intersection of a plane with a right circular [[cone]]. In mathematics, a cone extends to infinity, and goes in both directions from its apex.
Depending on the orientation of the plane relative to the cone, the conic section produced will be:
