Answer:
Rotations, reflections and translations.
Step-by-step explanation:
Rotations, reflections and translations are transformations that preserve the both the angle measurements and the lengths of the sides, so congruence is preserved.
Dilations are transformations that keep the angle measurements, but the side lengths change, so the transformation is similar, not congruent.
There are a lot of things that are equivalent to 16/81.
16/81 = 0.197530864
Or we can keep multiplying 2 to the numerator and denominator:
16/81 = 32/162 = 64/324 = 128/648
