Step-by-step explanation:
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.

Answer:
AB^2=(2*1)^2+(3-5)^2
= 1+4 = ROOT 5
you have solved only one part?
I have marked you as brainliest now give the full solution of the same!
