Usually sets of geometric transformations are considered such that each finite sequence of transformations in the set can be replaced by one transformation of the set, and a transformation inverse to any of those considered also belongs to the given set.
A geometric transformation is any bijection of a set having some geometric structure to itself or another such set. Specifically, A geometric transformation is a function whose domain and range are sets of points. Most often the domain and range of a geometric transformation are both R 2 or both R 3. Often geometric transformations are required to be 1-1 functions, so that they have inverses.. The study of geometry may be approached via the study of these transformations.
