A pentagon has five sides and five vertices
A pentagonal pyramid (5 sides and 1 base) has 6 faces, 6 vertices, and 10 edges (5 between the sides and 5 with the base).

The vertices refer to the points where to sides of a shape come into contact. So for example, a triangle has three vertices because its sides meet at three points. Each polygon also has the same number of vertices as sides (pentagon = 5 vertices, etc.)
This describes a square pyramid. It has a square for a base, and four triangular sides that meet at the "top" or upper vertex. It will then have 5 faces, which will be the 4 triangular sides and the square base. It will also have 8 edges and 8 vertices. Use the link below to see a drawing and you can count all the faces, edges and vertices.

There is no such shape. The only convex shape that has four faces is a tetrahedron, and that has four vertices, not 5.
It is a 5 sided pentagon
