Answer: Reflect over the y axis, then translate 1 unit right and 2 units down
Explanation:
We know that there is definitely a reflection over the y axis, so let's start with that.
Now, let's consider one of the vertices. A(2, 2) goes to (-2, 0), so we need to translate 1 unit to the right and 2 units down
If we check with the other 2 vertices, we can tell that the conditions are satisfied.
