Reflectional Symmetry is a property of certain geometrical objects that appears the same when mirrored or reflected along an axis. This axis has to cross the shape through the middle of that object dividing into equal halves.

In rotational symmetry, the object is identical when it is rotated by a certain amount.

The precise notions of symmetry have various measures and operational definitions. For example, symmetry may be observed
