plane curve formed by the intersection of a plane and a circular cone. The angle at which the plane cuts the cone determines whether the curve is a circle, ellipse, parabola, or hyperbola.

A plane curve obtained by cutting a cone with a plane. Depending upon the angle of the cone, the result is a circle, an ellipse, a parabola or a hyperbola.

(geometry) a curve generated by the intersection of a plane and a circular cone

a curve formed by the intersection of a plane and a right circular cone, or conical surface

A curve that has a sec- ond-degree equation and is defined in terms of the distance of its points from fixed points and/or lines. This includes circles, parabolas. ellipses and hyperbolas.

The section formed by the intersection of a plane and a cone.

A conic section is set of points that results from the intersection of a cone and a plane. Some conic sections include a point, ellipse, circle, parabola, and hyperbola.

A curve, as an ellipse, circle parabola or hyperbola, produced by the intersection of a plane with a right circular cone.

A curve formed by the intersection of a cone with a plane. This often results in a circle, ellipse or parabola. For more on conic sections, visit Mathworld's Conic Sections lesson.

In mathematics, a conic section (or just conic) is a curve that can be formed by intersecting a cone (more precisely, a right circular conical surface) with a plane. The conic sections were named and studied as long ago as 200 BC, when Apollonius of Perga undertook a systematic study of their properties.
