A piece of paper is folded and a cut is made as shown below. From the given responses indicate how it will appear when the paper will be opened:
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) →
The sheet is folded twice: the lower half up onto the upper half, then the left half over onto the right, so the cut is made through four layers in the top-right quarter. Opening the folds reflects the cut in each fold line:
The cut touches the vertical fold, so opening that fold joins it to its mirror image: one hexagon, centred on the middle line of the upper half.
The cut does not touch the horizontal fold, so opening that fold gives a second, separate hexagon in the lower half, right below the first.
