You might be interested to learn that there are infinite ways of cutting a square into quarters. Did you know that if you draw 2 perpendicular lines that both go through the centre of the square, then they always cut the square into quarters? See the pictures below; I've drawn you a few examples. If you keep spinning the lines a tiny amount you will get infinite answers!
