Conics, or conic sections, are the intersection of a plane with an infinite double cone. If that plane cuts both cones, it is a hyperbola. If it is parallel to the edge of the cone, you get a parabola. If neither is the case, it is an ellipse. The ellipse is also a circle if the plane is perpendicular to the altitude of the cone. Note that none of these are the case if the plane passes through the vertex of the cone.
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.
By "double right cone" do you mean one right cone sitting normal with another right cone upside-down atop the first cone? If so, then we you take that double right cone and intersect it with a plane at different angles, you get the conic sections. (i.e. hyperbola, parabola, elipse, circle)
An ellipse is produced.
If I understand your description correctly, a line.
No. A hyperbola is formed when a plane slices a cone perpendicular to the bases.
Prism
circles, ellipses conics which are formed by cutting a cone with a plane not passing through its nappus
Tilt of cutting plane is between (perpendicular to axis of the cone) and (parallel to the side of the cone).
A cutting plane line consists of a thick line shown through an area adjacent to the visible "cut" to clarify what is seen inside an object. Connected to the end of the line are two perpendicular lines with arrows showing the direction of view.
A line that is perpendicular to the segment of a plane and passes through the midpoint.
