The given description fits that of a triangular based pyramid which has 4 faces, 6 edges and 4 vertices
pyramid An pyramid is a geometric solid of the shape made famous by the royal tombs of ancient Egypt. It is a solid whose base is a polygon and whose lateral faces are triangles with a common vertex
A pyramid fits the given description
A vertex can be the corner of a polyhedron in which case at least three edges meet at a vertex.
An endpoint where two edges intersect on a polyhedron is called a vertex.
The definition of vertices is the plural vertex. A vertex is point of intersection of two or more lines. A vertex can also be used to describe the angular point of a polygon, polyhedron, or other shape.
pyramid
A pyramid has a polygonal base with all other sides being triangles. As the Egyptians famously demonstrated, a common pyramid has a square base with four triangles meeting at a vertex, but any polygon - regular or irregular - can be used as the base of such a polyhedron.

A pyramid seems to fit the description.
A polyhedron of which one face is a square, and the other faces are triangles with a common vertex.
A pyramid fits the given description
For every polyhedron, there is a dual which is a polyhedron that has:a face where the first had a vertex,a vertex where the first had a face,the same number of edges.A self-dual polyhedron is a polyhedron whose dual is the same shape.All pyramids, for example, are self-dual.
That's a "vertex" of polyhedron or of her cousin tipi.
A vertex can be the corner of a polyhedron in which case at least three edges meet at a vertex.
A pyramid
Edges meet at a vertex.
It may be called an apex, but that is really only appropriate for a simple convex polyhedron.
