However, in an oblique cone, there are exactly two families of parallel planes The sections of a cone 2 3. It is simple to parametrize it, and not too difficult to tell exactly what its location and dimensions are (when the cone is right-circular). When a cone is cut by a plane parallel to the axis of the cone the conic sections will be a Rectangular Hyperbola in Figur-A the plane-5 is parallel to the axis of the cone so as to produce a rectangular hyperbola as shown in Figure-F.
