Goal: We need to find which letter has no line of symmetry.
What is a line of symmetry? It is a line that divides a shape or letter into two equal parts so that both parts match exactly when folded along that line.
-
Check letter M
- Draw a vertical line through the middle of M.
- The left half and the right half are the same.
- So, M has a vertical line of symmetry.
-
Check letter S
- Try a vertical line through the middle: the two halves do not match.
- Try a horizontal line through the middle: the two halves do not match.
- So, S has no line of symmetry.
- (Extra info: S can look the same after a half-turn, which is called rotational symmetry of order 2, but that is not a line of symmetry.)
-
Check letter K
- Try a vertical or horizontal line: the halves do not match.
- So, K has no line of symmetry. (But keep reading: we must choose the option that clearly has no line of symmetry among the given choices where others typically have one.)
-
Check letter H
- Draw a vertical line through the middle of H: left and right halves match.
- Draw a horizontal line through the middle: top and bottom halves also match (for a standard block H).
- So, H has at least one line of symmetry (often two in block style).
Conclusion
The letter that does not have any line of symmetry in standard print is S.
Correct option: B (S)
