'Square Bisection' printed from https://nrich.maths.org/
Any line which passes though the centre of the square divides the
square into two congruent shapes. An example is shown below.
There are an infinite number of suitable lines (lines passing
through the centre, at any angle) so there are infinitely many ways
the square can be cut in half with a single straight cut.
