A paper is folded in half vertically (left over right). A hole is punched at position (30, 40). What pattern appears when unfolded?
Hole Punch Symmetry - Vertical Fold
Step 1: Paper folded vertically creates left-right mirror symmetry. Step 2: A hole punched at (30,40) goes through both layers. Step 3: When unfolded, the hole appears at (30,40) and its mirror (70,40). Result: Two horizontally aligned holes.
Question 14
A paper is folded in half vertically. A L-shaped cut from the folded edge. What pattern appears when unfolded?
An L-shaped cut on a vertical fold creates two mirrored L-shapes.
Question 15
A paper is folded in half vertically. A L-shaped cut from the folded edge. What pattern appears when unfolded?
An L-shaped cut on a vertical fold creates two mirrored L-shapes.
Question 16
A paper is folded with 4-fold rotational symmetry (pinwheel fold). A hole is punched near one edge. What pattern appears when unfolded?
