<p>Invariants are used in diverse areas of mathematics such as <a href="page.php?w=geometry">geometry</a>, <a href="page.php?w=topology">topology</a>, <a href="page.php?w=algebra">algebra</a> and <a href="page.php?w=discrete_mathematics">discrete mathematics</a>. Some important classes of transformations are defined by an invariant they leave unchanged. For example, <a href="page.php?w=conformal_map">conformal map</a>s are defined as transformations of the plane that preserve <a href="page.php?w=angle">angle</a>s.
