Answer:
(A) Quadrilateral 1 is congruent to quadrilateral 2 because the transformations are rigid.
Step-by-step explanation:
This is because since it's only being reflected across the y-axis and translated 8 units down, it's still an isometric.
Isometry or rigid transformation is the opposite of a non-rigid transformation and occurs during translations, reflections and rotations. Non-rigid transformations occur in dilations.
Isometry basically keeps all measure angles and distances of the polygon the same before and after a transformation.
