• A figure has line symmetry if a line can be drawn dividing the figure into two identical parts.
• The line is called a line of symmetry.
• A figure may have no line of symmetry, only one line of symmetry, two lines of symmetry or multiple lines of symmetry. Here are some examples.
• Line of Symmetry: A figure is said to have line symmetry, if by folding the figure along a line, the left and right parts of it coincide exactly. The line is called the line (or axis) of symmetry of the figure. A figure may have no line of symmetry, one line of symmetry, two lines of symmetry, three lines of symmetry and so on.
• Symmetry has plenty of applications in everyday life as in art, architecture, textile technology, design creations, geometrical reasoning, Kolams, Rangoli etc.
• Reflection and Symmetry: The line of symmetry is closely realted to mirror reflection.
When dealing with mirror reflection we have to take into account the left – right changes in orientation.
• Application in every day life: Symmetry has plenty of applications in every day life as in art, architecture, textile technology, design creations, geometrical reasoning Kolams, Rangoli etc.
