Question

If quadrilateral 1 is reflected across the x-axis and translated 8 units down to form quadrilateral 2, which statement is true?

Answer 1

(A) Quadrilateral 1 is congruent to quadrilateral 2 because the transformations are rigid.

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.
