Question 1
A square paper has its top-right corner folded to center. A hole is punched through the folded corner. What appears when unfolded?
Corner Fold Solution:
Step 1 - Understanding Corner Folds:
- Type: Corner-to-point fold
- Description: top-right corner folded to center
- Creates: 2 layers in triangular region
- Rest of paper: Single layer
- Only the folded region has double layers
Step 2 - Hole Punch:
- Position: punched through the folded corner
- Layers penetrated: 2 (in folded corner region only)
- Single layer regions: unaffected
- Creates 2 holes when unfolded
Step 3 - Unfolding:
- Unfold the corner back to original position
- First hole: Stays at punch location (center)
- Second hole: Appears where corner was originally (top-right)
- Result: Two holes: one at center, one at original corner position
Corner Fold Tips:
- Corner folds create partial overlap (not full paper)
- Only the folded region has double layers
- Useful for creating specific hole positions
- Common in origami and paper design
