Question

If area of Triangle ABC=0 then ,A, B and C , points form a triangle? Give reasons?

Answer 1

no it can't form triangle

Answer 2

If area of triangle is zero then these points are Collinear so these points cannot form a triangle.
Reasons... Formula of area = 1/2*b*h
Then base and height both would be equal to zero which is not possible in a triangle.
