Answer:
Figure ABCD is congruent to figure A’B’C’D’. So can say that Figure ABCD is similar to figure A’B’C’D’.
Step-by-step explanation:
It is given that Figure ABCD is reflected about the y-axis to obtain figure A’B’C’D’.
Reflection is a rigid transformation it means the size and shape of the figure remains same but reflected across a line of reflection.
In other words we can say that Figure ABCD is congruent to figure A’B’C’D’.

Corresponding parts of congruent figures are same.




Therefore, the correct statement is "Figure ABCD is similar to figure A’B’C’D’".
