Symmetry refers to a balance or correspondence of shape, size, and position on opposite sides of a dividing line or plane. It is a property of objects, shapes, and patterns that have identical or similar features on either side of an axis or center point. Symmetry can be found in nature, art, architecture, and mathematics, and it is often used to create aesthetically pleasing and harmonious designs. Examples of symmetry include the bilateral symmetry of animals, the rotational symmetry of flowers, and the reflective symmetry of a butterfly's wings.
