Step-by-step explanation:
Answer: It is given that point R is lying somewhere in between P and Q. Therefore all these points are lying on the same line segment PQ⎯ . Hence, for every situation in which point R is lying in between P and Q, it may be said that PQ =PR + RQ.
For an example,
PQ⎯is a line segment of 6 cm and R is a point between P and Q , such that it is 2 cm away from point Q. We can find that the measure of line segment PR⎯ comes to 4 cm. Hence, relation PQ =PR + RQ is verified.
