# What is Line Symmetry in Geometry?

Line symmetry is a fundamental concept in geometry. It is the property of an object or figure that remains unchanged when reflected over a line. It is also known as reflection symmetry, mirror symmetry, and rotational symmetry. Line symmetry is an important concept in geometric shapes and patterns, as it is often used to identify the different types of shapes and patterns in geometry.

## The Basics of Line Symmetry

Line symmetry is the property of an object or figure when it remains unchanged after being reflected over a line. This means that when an object is reflected over a line, its shape and orientation is still the same. This property is also known as reflection symmetry, mirror symmetry, or rotational symmetry.

When an object has line symmetry, it means that it can be divided into two halves that are mirror images of each other. This is known as a reflection line. This symmetry can also be extended to three, four, or more halves.

## Types of Line Symmetry

The two main types of line symmetry are reflection symmetry and rotational symmetry. Reflection symmetry is when an object is reflected over a line and the reflection is the same as the original. Rotational symmetry is when an object is rotated around a point and the rotation is the same as the original.

Reflection symmetry is a type of line symmetry where an object is reflected over a line and the reflection is the same as the original. This type of symmetry is often used to identify shapes and patterns in geometry.

Rotational symmetry is a type of line symmetry where an object is rotated around a point and the rotation is the same as the original. This type of symmetry is often used to identify shapes and patterns in geometry.

## Examples of Line Symmetry

One of the most common examples of line symmetry is a circle. A circle is an example of a shape with reflection symmetry, as it can be divided into two halves that are mirror images of each other. Another example of line symmetry is a square. A square is an example of a shape with rotational symmetry, as it can be rotated around a point and the rotation is the same as the original.

## FAQ

### How do you explain line of symmetry?

A line of symmetry is a line that divides a figure into two parts that are mirror images of each other. The two parts of the figure are exact reflections of each other when the figure is folded along the line of symmetry.

### How do you find the line of symmetry in geometry?

To find the line of symmetry, draw a line connecting the midpoints of two opposite sides of a shape. If the shape is a square or a rectangle, the line of symmetry will run through the center of the shape. If the shape is a triangle, the line of symmetry will be the line connecting the midpoints of two sides.

### What is symmetry explain with example?

Symmetry is when a figure has two or more parts that match up perfectly. For example, a rectangle can be divided into two parts that are mirror images of each other. This is an example of symmetry, as both parts are perfectly reflected when the figure is folded along the line of symmetry.

### What are the 4 lines of symmetry?

The four lines of symmetry are vertical, horizontal, diagonal, and rotational. Vertical symmetry is when a figure is divided into two parts that are mirror images of each other when the figure is folded along a vertical line. Horizontal symmetry is when a figure is divided into two parts that are mirror images of each other when the figure is folded along a horizontal line. Diagonal symmetry is when a figure is divided into two parts that are mirror images of each other when the figure is folded along a diagonal line. Rotational symmetry is when a figure is divided into two parts that are mirror images of each other when the figure is rotated around a point.
