Concept of topology rubber sheet geometry topology does not distinguish between a circle and a square but it does between a circle and a figure eight. Rubber sheet geometry noun a humorous name for topology. The main topics of interest in topology are the properties that remain. Topology branch of mathematics sometimes referred to as rubber sheet geometry in which two objects are considered equivalent if they can be continuously deformed into one another through such motions in space as bending twisting stretching and shrinking while disallowing tearing apart or gluing together parts.

Hence a square is topologically equivalent to a circle but different from a figure 8. For example a square can be deformed into a circle without breaking it but a figure 8 cannot. A circle can be stretched into a square with a rubber band but you can t stretch a figure eight into a circle without tearing. It is sometimes called rubber sheet geometry because the objects can be stretched and contracted like rubber but cannot be broken.

A sheet of rubber especially one from which shapes can be cut or which is used to protect against water dirt etc. A rubber durometer of shore 70a is the most commonly chosen material hardness for all applications.
