Question

Which of the lines in the picture are lines of symmetry of the figure?

• A. l, m and o
• B. l and n
• C. l, m, n and o
• D. m and o

Answer 1

The correct option is B l and n

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.
