Question 1
A transparent sheet is folded diagonally. Looking through the folded sheet, you see A butterfly wing (left half) visible.
What was the original pattern drawn on the unfolded sheet?
**Note:** Solid shapes = what's directly visible. Dashed shapes = what you see through transparency (reflections).
Step-by-Step Solution:
Step 1 - Reverse Reasoning:
- This is the OPPOSITE of previous problems
- Given: What you see through the folded transparent sheet
- Need to find: What the original drawing was
Step 2 - Using Transparency Symmetry:
- What you see through the folded sheet = original + reflection
- Therefore: original = what you see MINUS the reflection
- But careful: The reflection is ALSO part of the original
Step 3 - Pattern Decomposition:
- Visible: a butterfly wing (left half)
- Through transparency, you also see its reflection (right half)
- The reflection comes from the original drawing on the other half
- Therefore: Original must have had BOTH wings
Step 4 - Result:
- The original pattern was: A complete butterfly with both wings
