Best Answer

Circles, parabolas, ellipses, and hyperbolas are all conic sections. Out of these conic sections, the circle and ellipse are the ones which define a closed curve.

What a conic section?

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.

What is hyperbola in conic section?

The hyperbola is the curve at the boundary of the intersection of the conewith a cutting plane parallel to the cone's axis.


What is the focal radii?

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.
