1.	On a number line, co-ordinates of P, Q, R are 3,- 5 and 6 respectively. State with reason whether the following statements are true or false.(i) d(P,Q) + d(Q,R) = d(P,R) (ii) d(P,R) + d(R,Q) = d(P,Q)(iii) d(R,P) + d(P,Q) = d(R,Q) (iv) d(P,Q) - d(P,R) = d(Q,R)
Answer» On a number line, co-ordinates of P, Q, R are 3, $-$ 5 and 6 respectively. State with reason whether the following statements are true or false. (i) d(P,Q) + d(Q,R) = d(P,R) (ii) d(P,R) + d(R,Q) = d(P,Q) (iii) d(R,P) + d(P,Q) = d(R,Q) (iv) d(P,Q) $-$ d(P,R) = d(Q,R)
