# Concept of Symmetry

## Definition

Symmetry: Symmetry means that one shape becomes exactly like another after being flipped or turned.

Asymmetry: An irregularity or imbalance in the shape of an object or figure is called Asymmetry.

## Notes

### Symmetry:

Symmetry is an important geometrical concept, commonly exhibited in nature and is used almost in every field of activity. Artists, professionals, designers of clothing or jewellry, car manufacturers, architects, and many others make use of the idea of symmetry. The beehives, the flowers, the tree-leaves, religious symbols, rugs, and handkerchiefs - everywhere you find symmetrical designs.

Suppose we could fold a picture in half such that the left and right halves match exactly then the picture is said to be symmetrical. We can see that the two halves are mirror images of each other. If we place a mirror on the fold then the image of one side of the picture will fall exactly on the other side of the picture. A figure has line symmetry if there is a line about which the figure may be folded so that the two parts of the figure will coincide.

#### Symmetry and Asymmetry:

• When figures have evenly balanced proportions, they are said to be symmetrical.
• An irregularity or imbalance in the spatial pattern or shape or arrangement of an object or figure is called Asymmetry. For example, when a figure is divided into two unequal halves, it is a case of asymmetry.
