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.
