Question

Can we have a triangle of area 0 square units .what does it mean

Answer 1

acc to chapter 7 co ordinate geometry
if points of triangle r collinear area of triangle will be 0

Answer 2

no we can not have as any polygon is supposed to have area. if we put the formula of area, then also it is possible only if base and height is 0 unit and if the values are 0 unit then the line segments don't exist making polygon non existent.

hope it helps....
