Mirror iMage (reflection)
Look at the key P shown alongside.
When we flipped the key P, we get the Key Q.
The key Q is the mirror image or reflection of key P.
A reflection is like a mirror image. The figure does not change on
reflection. Only change is in the orientation. P Q
Here are some more examples of reflections or mirror image.
Remember
Reflection can be on
The mirror image is called reflection and the line of reflection, vertical, or horizontal
over the mirror line.
that is, the mirror line becomes line of symmetry.
