Question

In each of the following problem, a square transparent sheet with a pattern is given. How would the pattern appear when the transparent sheet is folded at the dotted line?

1. A.
2. B.
3. C. (Correct answer)
4. D.

Correct Answer

Option C — A tall rectangle with a dotted rectangle beside it. Inside: a triangle with its apex on the fold line, a second slanting line within it, and an arc bulging away from the fold line.

Detailed Solution & Explanation

The correct answer is option C.

Key Points

• The sheet is transparent, so nothing is hidden when it is folded — the pattern already on the near half and the pattern brought over by the fold are both visible, one on top of the other.
• The fold line is vertical and central, so the right half turns over onto the left half. Everything to the right of the line arrives mirrored left-to-right, and everything to the left of the line stays exactly where it was.
• Work out what each half contributes:
  • The left half holds the left portion of the triangle — its apex on the fold line and its long side running down to the bottom-left corner.
  • The right half holds the shorter right portion of the triangle together with the semicircular bulge. Reflected, that bulge now swells towards the left, and the triangle's short side becomes a second slanting line inside the big triangle.
• The folded sheet therefore shows a half-height, half-width rectangle carrying the large triangle, a second slanting line inside it, and a semicircular arc bulging away from the fold — which is option C.

Additional Information

• The reliable rule for transparent-sheet questions is that the fold line acts as a mirror: measure how far each feature sits from the line, and place its copy the same distance on the other side. Distance from the fold is preserved; distance from the sheet's edges is not.
• Because the sheet is transparent, the answer keeps every line from both halves. A common wrong turn is to erase whatever the folded half covers, which is what an opaque sheet would do.
• The curved bulge is the quickest discriminator: after folding it must point away from the fold line, so any option showing it curving back towards the fold can be dropped at once.
• Check the apex last. It sits on the fold line itself, so it is the one point that does not move — an option that shifts it has mirrored the wrong half.
