Step-by-Step Solution:

Step 1 - Independent Folds:
- Sheet 1: folded vertically → creates a vertical crease line
- Sheet 2: folded horizontally → creates a horizontal crease line
- Sheets are then stacked

Step 2 - Intersection Analysis:
- Where the two fold lines cross, you have a special point
- At this point, BOTH sheets have double layers
- This creates a region of increased opacity/visual emphasis

Step 3 - Visual Pattern:
- The vertical fold line appears as a vertical band
- The horizontal fold line appears as a horizontal band
- Their intersection creates a plus/cross shape
- Through transparency, this plus sign is clearly visible

Step 4 - Result:
- A cross/plus sign shape where both folds intersect

Step-by-Step Solution:

Step 1 - Independent Folds:
- Sheet 1: folded vertically → creates a vertical crease line

Step 4 - Result:
- A cross/plus sign shape where both folds intersect

Step-by-Step Solution:

Step 1 - Understanding Layer Ordering:
- When multiple transparent sheets are stacked, the TOP sheet is most visible
- Lower sheets are partially obscured but still visible through transparency
- Folding all sheets together preserves their relative order

Step 2 - Given Stack Order:
- Sheet A (red circle) - bottom
- Sheet B (blue square) - middle
- Sheet C (green triangle) - top

Step 3 - Visual Effect:
- When looking from above: You see ALL shapes
- But the top sheet's shape appears MOST prominent/clearest
- The green triangle appears to "float above" the others
- Lower shapes appear slightly faded/behind

Step 4 - Key Insight:
- Transparency doesn't eliminate depth ordering
- You can still perceive which layer is on top
- The top layer's pattern appears sharpest, with no other pattern above it

Step 5 - Result:
- The green triangle (top sheet in the stack) appears on top

Step-by-Step Solution:

Step 1 - Understanding Layer Ordering:
