    I have no idea what you are asking for. Your question is very vague.

    You could perhaps use a measuring device like a ruler for a short distance, or a measuring tape for longer ones.

    In case it is a line on a cartesian plane, you can use Pythagoras' Theorem.

    You could perhaps make use of the cosine rule if you have a triangle with an angle theta between the two other sides.



    Or the sine rule:



    As I said before, your question is vague. :(
