Reflection Symmetry
If we place a mirror on the line of symmetry we can see the complete image. So, we find that the mirror image or reflection of the image in the mirror and the given figure are exactly symmetrical.
This type of symmetry is called reflection symmetry.
The mirror line is the line of symmetry between the two figures. The mirror image of an object is the same but it appears in the opposite direction.
We note that the shapes in the above pictures are same but the other way round.
