Want to figure out whether two figures are congruent? There's a mathematically precise way to do this! Watch this tutorial on congruence transformations to learn more.
How do you know if one figure is similar to another? If you can find a similarity transformation that maps one figure to the other, then the figures are similar! Learn more about spotting similarity transformations with this tutorial.
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!
