the figure defined by intersection of a cone and a plane.

It sounds like this describes the conic section which is 2 straight lines intersecting at the origin [degenerate form of a hyperbola], but I may be misunderstanding the phrasing of the question.
It is a parabola.
circle and ellipse are closed curved conic section!, from bilal , Pakistan

A conic section is a curve formed by the intersection of a plane with a cone (conical surface). If the section is parallel to the base of the cone, the conic section has a fixed diameter and is a circle. Any other plane that does not intersect the apex is either a parabola, a hyperbola, or an ellipse.

Bi-truncated conic section, or doubly-truncated conic section
Parabolas have directori.
Any conic section.
A conic section is generated by the intersection of a plane with a double cone. The specific shape of the conic section (ellipse, parabola, hyperbola, or circle) depends on the angle of the plane in relation to the axis of the cone. The different conic sections result from different orientations of the cutting plane.
An ellipse is a conic section which is a closed curve. A circle is a special case of an ellipse.

The focal radii are the distances from the focal point of a conic section (such as a ellipse or a hyperbola) to a point on the curve along the major or minor axis. They are important in defining the shape and orientation of the conic section.
