Question

6.
Sketch proper figure and write the answers of the following questions.
(3) If X - Y - Z and l (XZ)=3√7 ,l(XY)=√7 , then l(YZ) =?​

Answer 1

Answer:

We know that

For any three-distinct collinear points P, Q and R, the point Q is said to be in between P and R if

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

l (PQ) + l (QR) = l (PR)

So,

(YZ)=2/7
