Which image will be formed after folding the rectangular sheet along the dotted line?
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) →
When the right half of the sheet is folded over the dotted line, everything on it is reflected in that line and lands on the left half. The right half’s lower slanting line comes over as a line rising from the bottom-left corner to the middle of the fold, and its upper slanting line falls on the left half’s own diagonal, so the two lines meet at the fold like a triangle pointing right.
