A(1,5),B(2,3)andC(−2,−11)

Now, AB=  

(1  

2

)+(2  

2

)

​  

=  

5

​  

 

BC=  

(4  

2

)+(14  

2

)

​  

=  

212

​  

 

CA=  

(1  

2

)+(16  

2

)

​  

=  

257

​  

 

As,CA>BC>AB

If points A,BandC are collinear then AB+BC=CA

But  

5

​  

+  

212

​  

 

=  

257

​  

 

So they are not collinear.
