Online College Courses for Credit

    Discuss how distance is the absolute value of the difference between two points on a line and how those two points define a segment of the line.


    Present the segment addition postulate.


    Provide examples that involve segments and their measures (ex. Points A, B, C, and D are collinear, in that order.  Find BC if AC = 2x + 4, BC = x, BD = 3x + 1, and AD = 17).


This packet should help a learner seeking to understand segments and their measures.
