Answer» We are given three points A(1,5),B(2,3) and C(-2,-11).We will find distance of AB BC AND CAand WE WILL CHECK THAT if AB +BC=CA..SO DISTANCE OF AB =root 5.BC=4. CA=3root5..So,AB+BC IS NOT EQUAL TO CA4+ROOT5not equal to 3 root5hence these points are not collinear...*********Thank. You ***********..::
