Solution & Step-by-step Explanation
Step-by-step Unfolding Process:
1. First Fold: The square paper is folded from right to left along the vertical centerline, reducing it to a half-width vertical rectangle on the left side (2 layers).
2. Second Fold: The paper is then folded from bottom to top along the horizontal centerline, leaving a small square in the top-left quadrant (4 layers in total).
3. Analyzing the Cuts:
* A right-angled triangle punch is made at the top-left corner of the folded sheet. Since the top-left corner of this quadrant represents the actual outer corners of the original unfolded paper, this cut will replicate at all four corners of the full sheet.
* Another triangular cut is made near the bottom-right corner of the folded quadrant. This corner corresponds directly to the exact center of the unfolded paper.
4. Unfolding back:
* Unfolding from top to bottom mirrors the central triangle vertically across the horizontal fold line.
* Unfolding from left to right mirrors the entire pattern horizontally across the vertical fold line.
This creates a symmetrical 4-way pattern with 4 outward-facing triangular shapes around the center and 4 small triangular cuts at each of the outer corners, which perfectly matches Option D.
