In the similaritytransformation of AABCto ADEF. ABC was dilatedby a scale factor of 1/2reflected across the !? 1,and moved through thetranslation [1.

Solution: C. Y-Axis
Analysis: In this case, the triangle is reflected across the Y-Axis. That's the reason why the triangle changes the orientation of the initial triangle.
Example: Point B reflects Point E. X=2 to X=-2. And the value of Y stands.
