Answer :- The answer is reflected . Triangle XYZ was dilated, then <u>reflected</u> to create triangle QAG.
Explanation :-
A dilation is a rigid transformation which creates a similar image as the real shape but with different size.
A reflection is a rigid transformation which creates a mirror image of the original shape without changing its size.
In the given picture we can see the size of ΔXYZ is reduced to ΔQAG byecause of dilation . Also ΔQAG looks like the mirror image of ΔXYZ (as it flipped horizontally).
Therefore if ΔXYZ is dilated then it must be reflected horizontally to create ΔQAG.
