Question Statement:
A square sheet of side length 10 cm is folded along the vertical midline x = 5, then along the horizontal midline y = 5 into the top-right quadrant [5, 10] x [5, 10]. A hole is punched at local coordinates (7, 8). Which of the following is NOT a hole coordinate on the unfolded sheet?
Options:
(A) (3, 8)
(B) (7, 2)
(C) (3, 2)
(D) (8, 7)
Answer Key:
D
Step-by-Step Solution & Explanation
The unfolded holes are reflections across x = 5 and y = 5: (7, 8), (2*5 - 7, 8) = (3, 8), (7, 2*5 - 8) = (7, 2), and (3, 2). The point (8, 7) is not one of these reflections.
