Question 1
A transparent sheet has patterns drawn on it. The sheet is folded horizontally along the center line.
Looking through the folded sheet, what pattern do you see?
**Note:** The dashed line shows the fold. Different colors show different layers.
Step-by-Step Solution:
Step 1 - Fold Analysis:
- Horizontal fold along center line
- Top half folds down over bottom half
- Transparent sheet allows seeing through all layers
Step 2 - Pattern Locations:
- Triangle originally at top half (position 50, 25)
- Circle originally at bottom half (position 50, 75)
- After fold: Triangle moves to bottom half (mirrored to 50, 75 region)
Step 3 - What You See:
- Bottom half now has TWO shapes: the original circle AND the folded-down triangle
- The triangle appears at the same location as the circle? Let's check carefully
- Triangle's new position: symmetric across horizontal axis → (50, 75)
- That's EXACTLY the circle's original position!
Step 4 - Transparency Effect:
- Triangle and circle are at the SAME location after folding
- Through transparency, you see BOTH shapes superimposed
- The circle also remains visible at its original location? Wait - careful!
- Actually, the original circle is now the BOTTOM layer at (50,75)
- The triangle is the TOP layer at the same spot
- You see a triangle overlapping a circle at the center
- Additionally, the top half is now empty (folded down)
Step 5 - Final Answer:
- Through the folded sheet: A triangle overlapping a circle at the center
- Correct answer: A triangle above a circle, with the circle appearing twice
