    Hello, really stuck on this problem, any help welcome




    AB is parallel to CD, this distance between them is X

    The square has side length X

    Prove that the angle shown on the diagram is 45 degrees

    Thank you

    You aren't given an angle of rotation for the square?

    I could be wrong, but it seems to me the angle marked in the diagram depends on the angle of rotation of the square.
