A '''parabola''' is a curve on a plane, consisting of all the points that are equidistant from a point called the ''focus'' and a line, called the ''directrix''.
A '''parabola''' is a [[curve]] on a [[plane]], consisting of all the points that are equidistant from a point called the ''[[focus]]'' and a line, called the ''[[directrix]]''.
It is a [[conic section]], the intersection of a [[plane]] and a [[cone]] where the plane is parallel one side of the cone.
