------
A plane intersects only one nappe of a double-napped cone such that it is parallel to the generating line and it does not contain the vertex of the cone.
A parabola is formed
---
Hyperbola is formed when
A plane intersects both nappes of a double-napped cone, and the plane does not intersect the vertex.
