## Symmetry

Symmetry is an important concept commonly exhibited in nature and is used almost in every field of life. This is a characteristic feature of many things in the world.

## What is Line of Symmetry?

**The line dividing the shape into two equal halves is called the line of symmetry. **In other words, A line about which a figure is folded so that the two parts of the figure will coincide is called the line of symmetry.

- A Symmetrical figure looks the same on both sides of the line of symmetry.
- Some figures can have one line of symmetry
- Some figures have two or more lines of symmetry
- And some figures have no lines of symmetry

Study the figure in which lines of symmetry are marked with dotted lines.

### Line of Symmetry of Plane Shapes

This is a **line of symmetry of plane shapes**.

### Line of Symmetry in Square

The square have **4 lines of symmetry**, shown in given figure:

## Line of Symmetry Examples

Some of the examples of the line of symmetry for different figures are given below-

- An
**equilateral triangle**have 3 lines of symmetry - A
**circle**have infinite lines of symmetry **Regular Pentagon**: five lines of symmetry- A
**Regular hexagon**has six lines of symmetry
