Zach and Naomi are studying geometric transformations. Zach is able to move the triangle $A$ to  $A'$  using the following sequence of basic transformations:

        1. Reflection across the x-axis.
        2. Reflection across the y-axis.
        3. Translation two units to the right.
Naomi claims that the same three transformations, done in any order will always produce the same result. Zach disagrees. Who is correct?

• Zach

• Naomi

• Both are correct

• Both are incorrect
