Segment Bisectors

Segment Bisectors


    Define midpoint and segment bisector, distinguishing the difference between the two.


    Review the midpoint formula: (, )


    Provide examples that demonstrate how to solve for unknown variables and segment lengths (ex. Points A, B and C are collinear, in that order.  is the segment bisector to segment = 6x + 4 and = 12x – 2.  Solve for x and find the length of and ).


This packet should help a learner seeking to understand segment bisectors.
