The reflection of the point in the xy planes:
As we learnt in conept
Co-ordinate planes -
The plane formed by X and Y axes is known as XY plane similarly with Y and Z axes is known as YZ plane and with X and Z axis is known XZ plane.
-
So XY- plane means z=0
The reflection is
as x- coordinate and y-coordinate does not change.
