Question

Which of the following is correct with respect to reflection symmetry of letters of the English alphabets?

• A. Letters O and X have reflection symmetry about both horizontal and vertical mirrors.
• B. Letters B, C, D, E and H have reflection symmetry about a horizontal mirror.
• C. All of the above.
• D. Letters A, H, I, M and W have reflection symmetry about a vertical mirror.

Answer 1

The correct option is C All of the above.

A shape has line symmetry when one half of it is the mirror image of the other half. A mirror line helps us visualise line symmetry.

If a mirror is kept vertically passing through the centre of letters A, H, I, M and W, the exact same reflection appears.

If a mirror is kept horizontally passing through the centre of letters B, C, D, E and H, the exact same reflection appears.

Similarly, letters O and X have reflection symmetry about both horizontal and vertical mirrors.
