Line Symmetry

Line symmetry, also known as mirror symmetry, is a concept in geometry where a figure is said to have line symmetry if one half of the figure is the mirror image of the other half when divided by a line. This line is called the line of symmetry.

Identifying Line Symmetry

To identify line symmetry in a figure, you can fold the figure along the line of symmetry. If the folded halves match exactly, the figure has line symmetry.

Examples of Line Symmetry

Common examples of figures with line symmetry include squares, rectangles, circles, and many letters of the alphabet such as A, H, and M.

Properties of Line Symmetry

Some important properties of line symmetry are:

• A figure may have one or more lines of symmetry.
• A figure with more than one line of symmetry may have rotational symmetry.
• If a figure has no line of symmetry, it is said to have no line symmetry.

Importance of Line Symmetry

Line symmetry is important in art, architecture, and design as it helps create balance and visual appeal in various forms of creativity.
