Question

how was figure a transformed to become figure a? 1. dilate 2. ? rotate reflect

Explanation:

First, dilation changes the size of a figure. Then, observing the orientation of Figure A and Figure A'', we can see that the orientation has changed in a way that is characteristic of a reflection (a flip over a line). Rotation would turn the figure around a point, but here the key change after dilation is the reflection - like flip.

Answer:

Reflect
