I'm assuming you are looking for the name of the conic section produced by this type of intersection?
If a right circular cone is intersected by a plane parallel to one edge of the cone, the resulting curve of intersection would be a parabola.
If the intersecting plane was parallel to the base, it would be a circle.
If the intersecting plane was at any angle between being parallel to the base and being parallel to an edge, it would produce an ellipse or part of an ellipse (depending on whether the intersection was completely within the cone).
i suppose it is an hyperbola
An ellipse is produced.
The intersection of a right circular cone and a plane that is parallel to the edge of the cone is a parabola. However, if the vertex of the cone lies on the plane, then the intersection is simply two intersecting lines.
If I understand your description correctly, a line.
When a cone is sliced parallel to the base then the shape produced is a circle. If the cone is sliced at an angle so that the cut goes completely through the cone then an ellipse is produced. If the cut is made perpendicular to the cone's base then the shape produced is a parabola.

A point.
When a right circular cone is intersected by a plane that passes through one vertex (nape) of the cone and is not parallel to any edge, the resulting shape is a parabola. This occurs because the plane cuts through the cone in such a way that it creates a curved section, which is characteristic of a parabola. The specific orientation and angle of the plane will determine the exact dimensions and location of the parabola within the cone.
A sphere intersected by a plane, An circular ellipsoid intersected by a plane, A cylinder, A cone, and many more shapes, some of which don't even have a name!
The intersection will consist of only one point.
It will be a hyperbola.
Yes, they are.

A parabola is the figure formed by the intersection of a circular cone and a plane that lies parallel to the edge of the cone. (the cone does not have to be a right [90°] circular cone).
