Pick the incorrect statement:
A point and its image are on the same side of the line of reflection.
One point has atleast two images for a single line of symmetry
Image of a point is a point that is equidistant from the line of reflection, i.e. if the plane is folded along the line of reflection, then the original point and its image coincide. This shows that the image and the original point lie on opposite sides of the line of reflection.
