When are two figures congruent? When you can move one on top of the other without changing its size or shape! Check out this tutorial to learn more about using isometries to map congruent figures onto each other.

If two figures have the same size and shape, then they are congruent. The term congruent is often used to describe figures like this. In this tutorial, take a look at the term congruent!

Not all transformations are created equal! Congruence transformations, or isometries, have a special property that distinguishes them from other transformations. This tutorial will show you what makes them special!
