            Reflections
                                                                                                         figure
            Stand in front of a mirror and look at it. You will see your image
            in it. This is your mirror image or reflection.                                               mirror

            Reflections are seen in many things like mirrors, glass, water                                image
            bodies, etc.  When you stand near a lake you see your own
            reflection in it.  You can also see the reflection of trees and                          mirror
            other nearby things in the lake. But the image in the reflection
            is flipped around.


                              Remember


                               The size of the object and
                               its reflection is always the                         object
                               same.                                                                   reflection
                                                                                                       (image)

              1.  Draw the reflections of the given shapes.

                  (a)                               (b)                            (c)










                  (d)                               (e)                            (f)






              2.  Mark a tick for the figures that are examples of reflections.
