What is a face?
A face is a flat (plane) or curved surface on a solid. It can also take the shape of a plane figure, such as a square or circle.
Examples:
To know how to represent the faces of a solid, read the concept sheet Constructing the Nets of Solids.
How do you know if a solid has plane or curved faces?
A solid with at least one plane (flat) face can slide.
A solid with at least one curved surface can roll.
A solid can have both plane and curved faces, so it can slide and roll.
