$d(A,B)=16, d(C,A)=9, d(B,C)=7$

From the information given below, find which of the point is between the other two. If the points are not collinear, state so.

$d(L,M)=11, d(M,N)=12, d(N,L)=8$

From the information given below, find which of the point is between the other two. If the points are not collinear, state so.

$d(X,Y)=15, d(Y,Z)=7, d(X,Z)=8$

From the information given below, find which of the point is between the other two. If the points are not collinear, state so.
