Question

Which postulate will you use to prove that PR = PQ + QR?

  1. Ruler postulate
  2. Segment addition postulate
  3. Division property
  4. Distributive property

hintHint:

Try to recall definition of postulates/properties given in options.

The correct answer is: Segment addition postulate


    SOL – Option (b)
    Segment addition postulate – It states that if a line segment has two endpoints, A and C, a third point B lies on the line segment AC if and only if this equation AB + BC = AC
    Since in figure given above, line segment has two end points namely P and R and third point Q lies on the line segment PR Þ PR = PQ + QR
