A circle, ellipse or similar shape.
A shape with 1 vertex, 1 edge, 1 flat face, and 1 curved face is a cone. The vertex is the tip of the cone, the edge is the circular base where the flat face meets the curved surface, and the flat face is the circular base itself. The curved face extends from the base to the vertex.

If you mean a cone then it has a flat base face and a circular face with one edge and one vertex
Faces-2 (1 flat face and 1 curved face), 1 curved edge, and 1 vertex.

A very common shape: the triangle. It is a flat plane that has only 1 face and always has 3 vertices or corners.
A sphere. A sphere is a solid figure that has no faces, edges, or vertices. This is because it is completely round; it has no flat sides or corners.
