A piece of paper is folded and a cut is made. From the given options, indicate how it will appear when opened.
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) →
The paper is opened by undoing the folds in reverse order, and at every opening the cut is reflected in that fold line. The circle was folded first along the horizontal line (bottom half up) and then along the vertical line (right quarter over to the left). The triangular cut sits on the vertical fold, so opening that fold turns it into a diamond on the vertical line; opening the horizontal fold then repeats the diamond below the centre.
