An<u> ellipse</u> is produced when you slice a cone with a plane that passes through only one nape of the cone, but is not parallel to an edge of the cone.
Step-by-step explanation:
The conic section which is produced when we slice a cone with a plane that passes through only one nape, but is not parallel to an edge of the cone is ellipse.
If the plane is perpendicular to the axis of the cone then the ellipse is changed to circle.
