Answer :
Final answer:
A stretching transformation is not a congruence transformation as it changes the size of the object while not preserving its shape.
Explanation:
Congruence transformation is a type of transformation in geometry that preserves size and shape. In the context of the question, a stretching transformation is not a congruence transformation because it changes the size of the object without preserving its shape. On the other hand, translating and rotating transformations are congruence transformations as they maintain the object's shape.
