When rotating won't do, simply flip.
And now for a different kind of rotation. Sometimes you need to rotate a shape, not by turning it around, but rather as if you were turning it over, to create a mirror-image reversed version. This is called flipping a shape. Yes, just like a pancake.
You can flip shapes horizontally or vertically.

When you flip a shape horizontally, the flip action occurs from side to side.

When you flip a shape vertically, the flip action occurs from top to bottom.
Look like fun? Try it yourself. It's time to practice.
