In Image X, a set of three figures, 1, 2 and 3, shows a sequence of folding a piece of paper. Figure 3 illustrates the process of cutting the folded paper. Choose a figure from Image Y that most closely resembles the unfolded form of figure 3.
Show answer & explanation
Correct answer: A
Explanation
To determine the unfolded form of the paper, we reverse the folding sequence step-by-step using symmetry:
• Step 1 (First Unfold): Unfolding the paper across the last fold line creates a mirror image of the punched cuts (circles and triangles) across that fold line.
• Step 2 (Final Unfold): Unfolding the paper completely across the remaining folds reflects all shapes into their corresponding quadrants/sections of the original square sheet.
Following this reflection across all fold lines, the symmetrical pattern of circles and triangles matches the arrangement shown in figure (A).
Therefore, the correct answer is (A).
