Answer:
Step-by-step explanation:
A(1,5),B(2,3)andC(−2,−11)
Now, AB=(12 )+(22 ) = 5
BC= (42 )+(142 ) = 212
CA= (12 )+(162 ) = 257
As,CA>BC>AB
If points A,BandC are collinear then AB+BC=CA
But
5 + 212 = 257
So they are not collinear.
if it help so plese mark it as brianlist and like it . i dont want follower but just want to increase the knowlage.
