A plane curve formed by the intersection of a right circular cone and a plane parallel to an element of the cone. A plane curve formed by the locus of points equidistant from a fixed line and a fixed point not on the line. (pr. pə-RA-bə-lə)Related links: A diagram of conic sections including a circle, an ellipse, a parabola, and a hyperbola. Also see arc, cone, cylinder, ellipse, hyperbole, mathematics, parabola, and sphere.<br><br>A plane curve formed by the intersection of a right circular cone and a plane parallel to an element of the cone.
