A square folded in half left-to-right is punched once near the top-right of the folded sheet. The unfolded pattern shows the two holes positioned:
Answer: Near the top, symmetric across the vertical crease
A top-right punch reflects across the vertical crease to a top-left position, keeping both holes near the top.
Folding a paper in half twice into quarters and cutting a notch from the center corner produces, when unfolded:
Answer: A diamond or square opening in the middle
The center corner of a quarter fold maps to the paper's middle, creating a central opening.
A once-folded paper is punched twice, each punch off the crease at different heights. How many holes appear when unfolded?
Answer: 4
Each off-crease punch doubles, so two punches through two layers yield four holes.
Which fold and punch combination produces exactly three holes when unfolded?
Answer: Three-panel fold with one off-crease punch
A three-panel (three-layer) fold with one punch through all panels gives exactly three holes.
An unfolded paper shows four holes arranged in a rectangle, all equally far from the center. The paper was folded:
Answer: Into quarters
A symmetric rectangle of four holes around the center is the signature of a quarter (two-fold) pattern.
A paper is folded in half and a hole is punched right at one end of the crease (on the edge). When unfolded, the result is:
Answer: A single half-hole notch on that edge
Punching at the crease's edge leaves a single notch on the paper's outer edge after unfolding.
If unfolding reveals holes that are mirror images across two perpendicular lines, the paper was folded:
Answer: Twice along perpendicular creases
Mirror symmetry across two perpendicular lines indicates two perpendicular folds (a quarter fold).
