A polyhedron with a polygon base and triangular sides that all meet at a common vertex is called a pyramid. The base can be any polygon (such as a triangle, square, or pentagon), and the triangular faces connect each edge of the base to the apex or common vertex at the top. Pyramids are named based on the shape of their base; for example, a pyramid with a square base is called a square pyramid.
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.
The vertex is a point of polygon or polyhedra that is formed by 2 lines or 3 edges on a polyhedron.
A tetrahedron (4 faces) or triangular bipyramid (5 faces).
A line that joins any vertex of a polygon (or polyhedron) to any vertex other than itself or adjacent ones is a diagonal.

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 seems to fit the description.
The vertex is a point of polygon or polyhedra that is formed by 2 lines or 3 edges on a polyhedron.
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.
No such thing A tetrahedron is a polyhedron composed of four triangular faces, three of which meet at each vertex. Similar to a pyramid but with a triangular base.
A polyhedron of which one face is a polygon of any number of sides, and the other faces are triangles with a common vertex.
A tetrahedron (4 faces) or triangular bipyramid (5 faces).
A line that joins any vertex of a polygon (or polyhedron) to any vertex other than itself or adjacent ones is a diagonal.
