Modern Geometry

    1. The problem statement, all variables and given/known data

    Define the following terms:
    a) Midpoint M of segment AB.
    b) Perpendicular bisector of a segment AB (you may use the term "midpoint" since ypu have just defined it).
    c) Ray BDbisects angle ABC (given that point D is between A and C)
    d) Points A, B, and C are collinear .
    e) Lines l, m, and n are concurrent .

    I need to use the five undefined geometric terms: line,point, "lie on", between, congruent.
    Please someone help. Thank you.

    2. Relevant equations

    3. The attempt at a solution

    I am lost. I used the dictionary, but still confused. I will apreciate any help.

    Have you tried wikipedia, mathworld, and/or planetmath?

    No, I tried only online dictionary, but not much help. I will try these above. I tried google as I as can, but....
    Thank you.

    No problem, at your level, I would first try wikipedia then planetmath. Mathworld sometimes has a tendency to go crazy with linking definitions and one starts losing sight of the forest. Good luck.
