Question

if figure b is transformed, which of these transformations will preserve congruence?translationrotationreflectionall of the above

Explanation:

Congruence-preserving transformations (rigid transformations) maintain the size and shape of a figure. Translation (sliding the figure), rotation (turning the figure), and reflection (flipping the figure) all preserve side lengths and angle measures, so they all preserve congruence.

Answer:

All of the above
