Three shapes are cut from a piece of cardboard and placed as shown above to form a combined shape. If the matchsticks on the inside of the shape are ignored, you will note that the combined shape is not symmetrical along any vertical axis.
However, a combined shape with vertical symmetry (again ignoring the inside matchsticks) can be created by flipping and/or rotating one of the shapes. Show how you would do this by moving only 3 matchsticks to create a combined shape that is vertically symmetrical.
The piece of cardboard in the middle is flipped vertically and then rotated 90 degrees clockwise.
