Question

A piece of paper is folded n times, corner to corner and a random pattern is cut out from the folded paper. Find the minimum number of lines of symmetry, the cut out figure obtained upon unfolding the paper would have.

Answer 1

Each fold acts as a line of symmetry imprinting the cut out on both sides across the crease.

Therefore, when n such folds are made, the figure is likely to obtain atleast n lines of symmetry. The lines of symmetry may increase based on the cut-out.
