Worksheet 8 of 10 (77% complete)

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

Question 2

Question 3

A transparent sheet has patterns drawn on it. The sheet is folded vertically 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 - Understanding Transparent Folding:
- Unlike opaque paper, transparent sheets allow you to SEE THROUGH the folded layers
- When you fold a transparent sheet, you see the superposition (overlap) of patterns from both halves
- This creates visual combinations that don't require unfolding

Step 2 - Initial Setup:
- Original sheet: A circle on left half, a square on right half
- The sheet is folded vertically along the center line
- After folding: Left half sits ON TOP of right half

Step 3 - Visual Analysis After Fold:
- The circle (originally on left) now overlays the right half
- The square remains on the right half (bottom layer)
- Through transparency, you see BOTH shapes simultaneously
- Where they overlap, you see a combined shape

Step 4 - Determining the Pattern:
- The circle moves to the right half (mirrored position)
- At the original square's location, the circle now sits above it
- Result: You see a circle overlapping a square
- The shapes are both visible due to transparency

Step 5 - Key Insight:
- Transparent folding creates VISUAL OVERLAP patterns
- You don't need to unfold to see the result
- The question asks: "What do you see through the folded sheet?"
- Answer: A circle overlapping a square at the center-right region
