What is a face?
A face is a plane or curved surface on a solid that is bounded by one or more edges.
A face can also be the base of a solid.
Examples:
To learn more about the bases of a polyhedron, read the Polyhedrons concept sheet.
What is an edge?
An edge is a line segment where two faces meet.
To help find the total number of edges in a solid, you can colour all the edges that you count.
Example:
What is a vertex?
A vertex is the point where the edges of a solid meet.
To help you find the total number of vertices in a solid, you can colour each vertex that you count.
Example:
How many faces, edges, and vertices do different solids have?
Here is the number of faces, edges and vertices of different solids.
