One: the point. Vertices are points. And it has one edge, which is circular.
The description given fits that of cones
A pentacontagon has 50 vertices (not vertices's!).

Pyramids end in one vertex and prisms end in multiple vertices. E.g. Rectangular Prisms are like cubes( multiple vertices) and pyramids are like cones (one vertex).
