What is symmetry in geometry?

Symmetrical elements are geometric objects on which symmetry operations are performed. Symmetry can be a point, a plane, or an axis. Symmetry operation is the movement of an object. After the movement, the object looks the same as before. The existence of symmetric operations means the existence of corresponding symmetric elements, and conversely, the existence of symmetry. The symmetry element means that a certain operation or a set of symmetric operations is possible.
