# Geometric Transformations

## Geometric Transformations

a one-to-one mapping of a straight line, plane, or space onto itself. 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. Such sets of geometric transformations form what is called a group of transformations. Examples of geometric transformations that form a group of transformations are the motions of a plane (or of a space), affine transformations, and projective transformations.

This case study shows that by using ToC for modeling and simulation of physical systems, the modeler will be aware of the fundamental geometric transformations and algebraic computations all the time; this is unlike modeling and simulations using graphical GUI based software which treats the models as a black box thus hides or abstracts away all the mathematical details.
