Explanation:

rotational symmetry

Thus, in 1 360o rotation, the crystal has repeated itself, or looks identical 4 times. We thus say that this object has 4-fold rotational symmetry. A Symmetry operation is an operation that can be performed either physically or imaginatively that results in no change in the appearance of an object.
