Question

Akula says"points A(1,3),B(2,2),C(5,1) are collinear" Do you agree with akula?why?

Answer 1

Let ABC form a triangle

ar.of triangle ABC=1/2|1(2-1)+2(1-3)+5(3-2)|

ar.of triangle ABC =1sq.units

aa ABC is forming a triangle

therefore,A,B,C are non collinear

therefore,I don't agree with Akhila
