Question

1. From the information given below, find which of the points between the other two.
If points are not collinear, state so.
(i)d(P,R) = 7 d(P,Q) = 10, d(Q,R) = 3
(ii) d(R,S) = 8 d(S,T) = 6 . d(R,T) = 4​

Answer 1

Step-by-step explanation:

let A ,B,C be three points for the point's to be collinear

AB+BC should be equal to AC

thus,

I) PR =7. PQ = 10. QR = 3

for the point's to be collinear

PR+QR should be equal to PQ

here ,

PR+QR = 7+3 = 10 = PQ

thus the points are collinear

ii). In this case the points are not Collinear because ,

for the point's to be Collinear ST+RT =SR

HERE,

ST+RT = ≠. SR

6+4=10 ≠8
