Question 1
A square paper is folded 1/3 from left edge toward right. A hole is punched in the overlapping section. What is the pattern when unfolded?
Competition-Level Asymmetric Folding Solution:
Step 1 - Asymmetric Fold Analysis:
- Fold: 1/3 from left edge toward right
- This is NOT a center fold
- Creates unequal overlapping regions
- Layer structure: complex partial overlap
Step 2 - Geometric Setup:
- Paper width: 100 units
- Fold line at: x = 33.33 (1/3 from left)
- Left section (0-33.33): single layer
- Middle section (33.33-66.66): double layer (overlap)
- Right section (66.66-100): single layer
Step 3 - Unfolding Result:
- Two holes at asymmetric positions
- Not centered symmetry
- Result: Two holes asymmetrically positioned
Competition Insight: Asymmetric folds break the simple 2^n pattern and require careful region-by-region analysis.
