A dodecagon (12 sided polygon)
1 + number of sides/vertices the base shape has A square-based pyramid has 5 vertices, for example.
A pyramid can have any polygonal shape for its base. A pyramid with an n-sided polygonal base has n+1 vertices and n+1 faces.Assuming you're talking about a square pyramid, there are 5 faces and 5 vertices.
If the pyramid has a triangular sides then truncate each vertex (cut off a small pyramid shape from the vertices).If the pyramid has a quadrilateral base then truncate 3 vertices.If the pyramid has a pentagonal base then truncate 2 vertices.If the pyramid has a hexagonal base then truncate 1 vertex.If the pyramid has a heptagonal base then it is already an octahedron.If the pyramid has an base with 8 or more vertices then slice off the section formed by joining the apex and two vertices from the base which are six apart. This makes the base heptagonal and therefore the shape is an octahedron.
A pyramid actually has five vertices. A pyramid is made from a square base, and has four triangular sides. The number of vertices is determined by how many points there are in the shape.
A pyramid with a quadrilateral base.

It depends on the shape of the base. A pyramid that has a base with n vertices (an n-gon) will have n+1 vertices in all.

Depends on the shape of the base of the pramid. Add the vertices of the base and add one. For example, the pyramids in Egypt have a square base. 4+1 = 5 vertices

A pyramid with a quadrilateral base.
A square based pyramid.
A pyramid with a quadrilateral base. * * * * * A triangular dipyramid or a quadrilateral based pyramid.
A square-based pyramid would fit the given description. (A triangular prism would have 9 edges and 6 vertices)
An octagonal pyramid has 9 vertices. The base of this shape is an octagon, which will give it 8 vertices when the triangles that form the sides are considered. Those triangles will lead up to the apex (top) of the pyramid, and that will be the 9th vertex.
A rectangular (or square) pyramid. Or, in fact, a pyramid with any quadrilateral as base.
