Question

3. From the information given below, find which of the point is berwcon the other the
If the points are not collinear, state so
1) d( PR) d( P, Q) d( QR)​

Answer 1

Step-by-step explanation:

(i) 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

∴ d(P, Q) = d(P, R) + d(Q, R)

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

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