When we study two dimensional coordinate geometry, then the set of all points in xy-plane is the universal set.

If D ,Ea n dF are the mid-points of sides BC, CA and AB respectively of a A B C , then using coordinate geometry prove that Area of △DEF= 1/4 (Area of △ABC)

[NiCI_(2){P(C_(2)H_(5))_(2)(C_(6)H_(5))}_(2)] exhibits temperature dependent magnetic behaviour(paramagnetic//diamagnetic) The coordination geometries of Ni^(2+) in the paramagnetic and diamagnetic states are respectively .

ABC is a triangle and AD is the median. If the coordinates of A are (4,7,-8) and the coordinates of centroid of triangle ABC are (1,1,1) what are the coordinates of D? (A) ((-1)/2,2,11) (B) ((-1)/2,-2,11/2) (C) (-1,2,11) (D) (-5,-11,19)
