Imaginary lengths may be unintuitive but negative is pretty simple.
The idea of negative measurements (meaning "opposite direction along a line") as is well understood before children study geometry. Kindergarteners learn "left" vs "right" and "forward" vs "backward".
I agree with other poster about the value of showing negative and positive lengths visually in the same diagram.
