Given a compass, a straightedge, and a line segment AB of length 3, how could you draw a line segment with a precise length of the square root of 3?

I won't spoiler this answer cuz it's offered in jest.
Start instead with a line AB of length 1 and construct a line of length sqrt(1).
Then scale up by factor of three.
