# Line of Symmetry – Definition, Types and Examples

## 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
