If you can reflect a figure over a line and the figure appears unchanged, then the figure has reflection symmetry or line of symmetry. The line that you reflect over is called line of symmetry. A line of symmetry divides figure into two mirror images.
So, in the given figure none of the lines l,m or n shows above mentioned properties.
