    Determing whether symbols represent a ray.

    "Point R is between points P and S. Are ---> and ---> the same ray, opposite rays, or neither the
    PR PS
    same nor the opposite." Well I know through reason that if R is inbetween, then P < R < S or
    S < R < P is true. And, observing the notation given,I believe the endpoint is P. I feel certain that the answer is they are the same rays. The last choice of answer just seems illogical. How can the two things be neither the same nor the opposite; it seems like if they were, the they would be nothing? Clearly--at least to me--they have to be something, because there is notation denoting something. If this ramble seems erroneous, please kindly inform me.
