Question 1
A paper is folded in half horizontally (bottom over top). A hole is punched at position (40, 30). What pattern appears when unfolded?
Hole Punch Symmetry - Horizontal Fold
Step 1: Paper folded horizontally creates top-bottom mirror symmetry.
Step 2: A hole punched at (40,30) goes through both layers.
Step 3: When unfolded, the hole appears at (40,30) and its mirror (40,70).
Result: Two vertically aligned holes.
