Ques: What is the length of AB, if line l is the segment bisector and AO = 6 units?

example of Segment Bisector
  • A. 13 units
  • B. 6 units
  • C. 12 units
  • D. 14 units

Correct Answer: C


  • Step 1: Line l divides AB into two equal parts and O is the midpoint of AB.
    [As the segment bisector passes through the midpoint of the segment.]
  • Step 2: AB = 2(AO) = 2(6) = 12 [Substitute AO = 6.]
  • Step 3: So, the length of AB is 12 units.
