After triangular folding and punching, the correct pattern will be similar to option (A).

After folding and punching the paper, the pattern's reflection will be formed in all four quadrants. Option (D) is the most accurate pattern.

The punch marks on the paper flip according to the folds. In this case, the correct pattern is (B).

The cuts made after folding the paper are repeated as mirror images when the paper is unfolded. The correct answer is (D).

The paper is folded and rectangular punches are made. Upon opening, these will form rectangles in a symmetric line as shown in option (A).

Option (C) is the correct pattern.

Upon unfolding the punched paper, the pattern in option (B) is obtained.

Upon unfolding, the cutting marks will appear symmetrically around, which matches option (A).

After folding and cutting the paper, it creates a symmetrical pattern that is repeated across the entire paper. According to the laws of mirror images, the correct answer is (C).

Upon folding the transparent sheet, the triangular patterns will overlap each other, as shown in option (D).

The paper is folded vertically and then horizontally, creating 4 parts. Based on the position of the cut, it creates mirror images in each part. The correct answer is (B).

The correct pattern is shown by option (B).

When the paper is unfolded, the position of the punch creates a mirror image, resulting in the correct option (A).

The holes punched after folding the paper appear as mirror images when the paper is unfolded. Upon geometric arrangement, option (B) is correct.

The alignment of the triangles is correctly shown in option (D).

Upon unfolding, a large punch in the center and small punches at the corners will appear similar to option (C).

The correct pattern is option (D).

The correct pattern is option (A).

The paper is folded and punched. When the paper is unfolded completely, the holes will maintain a circular symmetry as shown in option (B).

The paper is folded in a specific pattern. Upon unfolding, the position of the hole follows the law of symmetry, which corresponds to option (D).
