Which of the following letters does not have the vertical line of symmetry?

(A)

M

(B)

H

(C)

E

(D)

V

Detailed Answer with Explanation:

What is a vertical line of symmetry?

It is a straight line drawn from top to bottom through the middle of a figure. If the left half and the right half look exactly the same (like a mirror image), then the figure has a vertical line of symmetry.

How to check?

Imagine folding the letter along a vertical line through its center. If both halves overlap perfectly, it has vertical symmetry. If not, it does not.

Test each option

  1. M — The two slanted strokes on both sides are balanced. Folding down the middle makes the left and right parts match.
    Conclusion: M has a vertical line of symmetry.

  2. H — Two upright lines with a bar in the middle. The left side and right side are the same.
    Conclusion: H has a vertical line of symmetry.

  3. E — A long vertical bar with three horizontal arms on the left. The right side is empty, so the two halves do not match if you fold vertically.
    Conclusion: E does not have a vertical line of symmetry.

  4. V — Shaped like an open triangle pointing down. The two slanted sides are mirror images across the middle.
    Conclusion: V has a vertical line of symmetry.
