### Faces, Edges and Vertices Notes

There are differences in the definition of what a face is depending on which country you are in.

In some countries, a face is defined to be a flat surface and cannot be curved.

In other countries, it is possible to have curved faces.

This irregularity has a knock-on effect on edges, which are the place where two faces meet.

As a vertex is a place where two or more curves, lines or edges meet, this is also affected by ambiguities.

#### Different Definitions Create Issues!

The Problems with Cones

• A cone can either have 1 or 2 faces depending on whether you count the curved 'face'.
• A cone can also either have 0 or 1 edges depending on whether you count the curved 'face'.
• A cone can either have one apex or vertex, or none as there are no edges that meet together.

The Problems with Cylinders

• A cylinder can either have 2 or 3 faces depending on whether you count the curved 'face'.
• A cylinder can either have 0 or 2 edges depending on whether you count the curved 'faces'
