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.

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 polyhedron with a polygon base and triangular sides that all meet at a common vertex is known as a pyramid. The base can be any polygon, such as a triangle, square, or pentagon, and the triangular sides are called lateral faces. The vertex where all the triangular faces converge is referred to as the apex of the pyramid. Each type of pyramid is named based on the shape of its base, such as a triangular pyramid or a square pyramid.
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.

Edges meet at a vertex.
