alleryA circle can be folded along how many different lines so the halves match?
AExactly two
BExactly four
CExactly eight
DInfinitely many
Answer & Solution
Correct answer: D. Infinitely many
1. Any line through the centre of a circle folds it into two matching halves.
2. There are endlessly many such lines through the centre.
3. So the count cannot be a fixed number like two, four or eight.
