【Question 9】
Draw two straight lines to divide a square into four identical and equal-sized shapes, there are $\qquad$ ways to do this.
【Analysis and Solution】
Graphical cutting and rearrangement.
As long as these two lines both pass through the center of the square (the intersection of the square's diagonals) and are perpendicular to each other; these two lines will definitely divide the square into four figures of the same shape and size; therefore, there are infinitely many ways to draw two lines to divide the square into four figures of the same shape and size.
