1.	Sridha says points A(1,3), B(2,2) ,C(5,1) are collinear Do you agree with sridha and why?
Answer» ong>Step-by-step explanation: If A, B and C are collinear, then - AREA of ∆ABC = 0 x1(y2-y3) + x2(y3-y1) + X3(y1-y2) = 0 1(2-1) + 2(1-3) + 5(3-2) = 0 1(1) +2(-2) + 5(2) = 0 1-4+5=0 -5+5= 0 Yes, area of triangle ABC is zero. So. the GIVEN points are collinear. So, Sudha is right.

Answer»

ong>Step-by-step explanation:

If A, B and C are collinear, then -

AREA of ∆ABC = 0

x1(y2-y3) + x2(y3-y1) + X3(y1-y2) = 0

1(2-1) + 2(1-3) + 5(3-2) = 0

1(1) +2(-2) + 5(2) = 0

1-4+5=0

-5+5= 0

Yes, area of triangle ABC is zero.

So. the GIVEN points are collinear.

So, Sudha is right.
