Q7: Which of the shapes is divided into two mirror halves by a dotted line?

(a) A and B
(b) A and C
(c) B and C
(d) All of these
Ans: (c)

• Shape A: A symmetric star, but the given dotted line may not create perfect mirror halves.
• Shape B: A butterfly, which has clear bilateral symmetry along the dotted line.
• Shape C: A hexagonal shape that appears symmetric along the given dotted line.

Since B and C are properly divided into two equal mirror halves by the dotted line, the correct answer is:

Answer: (c) B and C
