Answer: HG, CD, and PN
Explanation:
The only transformations that we have are:
Reflections, rotations and/or translations.
You should notice that none of these transformations are dilations/contractions. This means that the length of the segment will remain constant.
Then the possible images of AB after the sequence of transformations, are the segments that have the same length as AB.
The length of AB is 4 units.
The segments with the same length are:
HG, CD and PN
So any of those could be the image of AB after the transformations.
