If a is the long side and b is the short side of a rectangle. Halving the rectangle will make the long side b and the short side 1/2 a. If the ratio is preserved when halving, we get: a/b=b/(1/2 a) a2*=2*b2 a2*/*b2=2 a/b=sqrt(2)

Wait, is that true? Is there something special about that ratio in particular that lets it conserve ratio when dividing?
And IIRC, A0 is 1m²
There also is B0, which is exactly 1 by the root of 2 meters.
Beautiful.
Yes it’s true. It’s the square root of 2, which is why it works.
