Cumbersome, but maybe we can make it.
Rename the vertices of the segment as e.g. P1 and P2, but show their labels as A and B.
Rename the segment as g, but display its label as f.
Create a 2 variables function for the input box, like e.g.
rep2_{1}(AB, f) = f cos(30°) + AB
Then enter SetValue(rep2_{1},?) to set it as undefined, but still be a function in 2 variables.
Then try with numerical testing to see if the student entry was correct.
Can this work?
See attached file, and try to enter in the 2nd input box terms containing AB or f.
In an InputBox, when the name of a variable have more than one letter, GeoGebra doesn't interpret correctly this but before it was not a problem. It was even possible to directly write "Distance(A,B)".
Yes, we've "locked down" Input Boxes a bit recently
as poor workaround you can rename AB to D_AB or A_B and type it in inputbox
or to use a text for input and a script with parsetonumber()
