alleryHoles are punched in a folded square sheet, which is then opened. What is the fold line?
AA line of rotation
BA line of tangents
CA line of symmetry
DA random crease
Answer & Solution
Correct answer: C. A line of symmetry
1. Holes punched through a folded sheet appear in matching pairs when it is opened.
2. Each hole is the mirror image of its partner across the fold.
3. So the fold is a line of symmetry, not a rotation line or a random crease.
