A pyramid is a generic term. There are pyramids with triangular bases, square or rectangular or quadrilateral bases, pentagonal base and so on.
A pyramid whose base is a polygon with n sides has n+1 sides (which are the same thing as faces), and n+1 vertices.
A rectangular based pyramid has 5 faces, 8 edges and 5 vertices whch is the plural of vertex.
A triangular pyramid has 4 faces 4 vertices and 6 edges.

A rectangular pyramid has five faces. Sides are the same things as faces. A pyramid with a triangular base has 4 faces. This is the more common type of pyramid in mathematics, as it is a platonic solid.
A pyramid has 3 or 4 sides.
5 faces (sides) 9 edges 6 vertices
A pentagonal pyramid has 6 faces.
20 faces and 10 sides
A pyramid is not normally circular but if you mean a cone then it has 1 vertex, 1 circular edge and 2 faces.
Faces = sides = 5. Edges = 8
A pyramid with a base of 10 sides will have 10 vertices along the base. In addition to these base vertices, a pyramid will have one vertex at the apex, where all the triangular faces meet. Therefore, a pyramid with a 10-sided base will have a total of 11 vertices.
A square pyramid has five faces. There is the square that forms the base, and four triangular sides.
