The term '''congruent''' describes [[shape]]s and [[line]]s which are identical to one another. Congruent [[polygon]]s have equal [[angle]]s and sides that are the same length.

So, congruent figures have they same size and shape, but different positions. They can be moved into each other by [[translation]]s, [[rotation]]s and [[reflection]]s. These movements are called [[isometry|isometries]].
