This is a hint to help you show that you've found all of the different
transformations:Once you think you've found them all, try drawing
the upside-down `L' shape on a piece of squared paper, and draw the effects of
all of
the different transformations on that shape on the same piece of squared paper.
What happens if you apply
or
to one of the shapes now? How does this
help you?
