Question

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

1) d(P,Q)+d(Q,R)=d(P,R)
2) d(P,R)+d(R,Q)=d(P,Q)
3) d(R,P)+d(P,Q)=d(R,Q)
4) d(P,Q)-d(P,R)=d(Q,R)

let me know the answer guys
​

Answer 1

Step-by-step explanation:

Answer : Since, the coordinates of P, Q and R are 3, -5 and 6 respectively. We know that 6 > 3 > -5. So, this statement is false.

Answer 2

1 true

2 false

3 true

4 false
