## If you can reflect (or flip) a figure over a lime** **and the figure appears unchanged, then the figure has reflection **symmetry** or **line symmetry**. The **line** that you reflect over is called the **line of symmetry**. A **line of symmetry** divides a figure into two mirror-image halves.

In the given figure, lines $l$ and $n$ divide figure into two mirror-image halves.

Hence, they are lines of symmetries.
