Question 1
A transparent sheet is folded in thirds (accordion/Z-fold). Different sections have different patterns.
Looking through the folded sheet, what pattern do you see?
**Note:** Different colors represent different patterns. Arrows show fold directions.
Step-by-Step Solution:
Step 1 - Accordion Fold Analysis:
- Z-fold (accordion) creates 3 stacked sections
- Each section may have different patterns
- Through transparency, patterns from ALL sections superimpose
Step 2 - Stripe Superposition:
- Section 1: vertical stripes
- Section 2: horizontal stripes
- Section 3: vertical stripes again
- When stacked: vertical + horizontal = grid/plaid pattern
Step 3 - Visual Result:
- The overlapping creates a checkerboard-like grid
- Where both vertical and horizontal stripes exist: darker intersection
- Result: A plaid/grid pattern (overlap of vertical and horizontal stripes)
