Answer:
Reflections
Step-by-step explanation:
1- For translation:
A translation can be a composition of a reflection as it can composed by two reflections over parallel lines.
These lines should be separated by a distance equal to half the distance of translation
2- For rotation:
A rotation can be a composition of a reflection as it can composed by two reflections over non-parallel lines.
These two non-parallel lines should intersect at the point representing the center of rotation
