    Simple proof regarding segments, rays and lines

    Prove that for A not equal to B, segment AB is a subset of ray Ab, which, in turn, is a subset of line AB.

    I'm having trouble getting this one going. I think that I need to show that every element of segment AB is an element of ray AB, which is an element of line AB. Any help is appreciated.

    Well a segment has a beginning and an ending. A ray has a beginning but not an ending, Thus is the ray has both points then the segment is contained in the ray. Same can apply with a line. I believe in theory that should be correct.
