A transparent square sheet has a design of a right-angled triangle positioned in the left half and a standalone vertical straight line positioned in the right half. How would the sheet appear when it is folded along the central vertical dotted line from right to left?
- AThe vertical straight line will overlap directly onto the left half, running vertically through the interior of the right-angled triangle.
- BThe right-angled triangle will disappear entirely.
- CThe vertical straight line will remain on the right side only.
- DThe right-angled triangle flips upside down completely.
Solution & Step-by-step Explanation
When a transparent sheet is folded from right to left along a central vertical dotted line, the graphics on the right half are flipped horizontally (mirrored) onto the left half. Since a vertical straight line looks identical when mirrored, it will simply shift over to the left side and overlap across the existing right-angled triangle design.
