The term that best describes it is an "oxymoron". A solid shape with one base opposite a single point is not a prism so such an object cannot exist.
vertex
===> "circle", with center at the "single point" and radius of the "certain distance".
The answer will depend on what the "certain distances" are for each point.

Locus
An object positioned beyond the focal point of a convex lens will produce a real and inverted image between the focal point and the lens. An object positioned at the focal point will produce no image. An object positioned between the focal point and the lens will produce a virtual and upright image beyond the lens.
The major axis is the longest possible segment you can draw from one point on the ellipse ,through the center, and to the opposite point.
The answer will depend on what the "certain distances" are for each point.

The artist carefully positioned the buildings in the painting so that their lines converged at a single vanishing point on the horizon, creating a sense of depth and distance.
Altitude
the magnifying glass must be positioned so as to focus the light from the sun on a single point (ex. kindling), causing heat and hopefully, a small fire
