Question

If d(PR) = 7. d(PQ) = 10. d(QR) = 3, find which of the point is between the other two.​

Answer 1

Answer:

the number between them is 12

Answer 2

Answer:

We have,

d(P,R)=7;d(P,Q)=10;d(Q,R)=3

Now,

d(P,R)+d(Q,R)=7+3

Or,

d(P,R)+d(R,Q)=10

so,d(P,Q)=d(P,R)+d(Q,R)

Hence,the points P,R and Q are collinear.

The points R is between P and Q i.e.,P-R-Q.
