It has six vertices and nine edges. A rectangular pyramid has

**5 faces**. Its base is a rectangle or a square and the other**4 faces**are triangles. It has 8 edges and 5 vertices.Likewise, people ask, how many faces does have a sphere?

All of these figures are curved in some way, so they have no edges or vertices. What about their faces? A sphere has no faces, a cone has one circular face, and a cylinder has

**two**circular faces. Therefore, the number of faces increases by one from one figure to the next.What is the meaning of faces in math?

In any

**geometric**solid that**is**composed of flat surfaces, each flat surface**is**called a**face**. The line where two**faces**meet**is**called an edge. For example, the cube above has six**faces**, each of which**is**a square.What are the vertices of a shape?

**Vertices**is the plural form of the word

**vertex**. A

**vertex**is a single point. It joins edges together in a

**shape**. Often, we also might call it a corner or just a point. An edge is a line segment.
