Clipart images of conic sections, or conics, in the shape of an ellipse. Conics are obtained by taking a cone, or conical surface, and intersecting it with a plane. Conic ellipses are retrieved when the intersecting cone and plane create a closed curve, except for the case where the plane that creates the closed curve is parallel to the plane of the circle created by the cone. In this case, a conic circle is created.
