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 translation moves every point of a figure or a space by the same amount in a given direction. A reflection against an axis followed by a reflection against a second axis parallel to the first one results in a total motion which is a translation. In Euclidean geometry, a translation is a function that moves every point a constant distance in a specified direction. (Also in Euclidean geometry a transformation is a one to one correspondence between two sets of points or a mapping from one plane to another.
