A transparent square sheet shown above is folded along the dotted line. The folded sheet will look like ________.
Attempted by 142 students.
Show answer & explanation
Key idea: Folding along the vertical dashed line produces a mirror image of the left half on the right half.
Steps to check which picture is correct:
Identify distinctive features on the left side before folding: the curved arc that meets the fold and the small tick marks (short vertical and horizontal notches).
Reflect those features across the fold (mirror horizontally). Every point and notch on the left moves to the corresponding symmetric position on the right at the same distance from the fold.
Compare this mirrored arrangement with the given choices. The correct picture must match both the shape of the curved overlap and the exact relative positions and orientations of the small notches.
Conclusion: The image that shows the left half exactly mirrored onto the right, with the curved arc and the small vertical and horizontal notches in the correct relative positions, is the correct folded shape.
