Definition (keystage 2)
A way of transforming a shape in the same way that a mirror does.
The reflection of a shape in a mirror line is an identical shape which has been flipped over.
When an object is placed a certain distance in front of a mirror, its image in the mirror appears the same distance away from edge of the mirror. Likewise, all the points on a shape and all the points on its image are same distance away from the 'mirror line'.
