A(3,1,6);B=(1,3,4) Mid-point of AB=(2,2,5) lies on the plane. and d.r's of AB=(2,−2,2) d.r's of normal to plane =(1,−1,1). Direction ratio of AB and normal to the plane are proportional therefore, AB is perpendicular to the plane ∴A is image of B Statement- 2 is correct but it is not correct explanation.
