ANSWER:-
We know that in a plane mirror the object is of the same size as that of object and we also know that Magnification = Height of image / Height of object = V/u where V is the object distance and u is the image distance and let magnification be M and we also know that height of image is same as that of object so cancelling out we get 1 Magnification= 1= V/u u=V therefore from above we can say that the object distance is same as that of image distance and hence proved

Answer:
Thus, the image I in a plane mirror is as far behind the mirror as the object O is in front of it. In other words, the distance of the image from the plane mirror is equal to the distance of the object from the plane mirror. We will prove this fact by using the laws of reflection and simple geometry.
