A homeomorphism, also called a continuous transformation, is an equivalence relation  and one-to-one correspondence 
 between points in two geometric figures or topological
 spaces  that is continuous  in both directions.
 A homeomorphism which also preserves distances is called an isometry .
 Affine transformations  are another type
 of common geometric homeomorphism.
The similarity in meaning and form of the words "homomorphism "
and "homeomorphism" is unfortunate and a common source of confusion.
