Answer:
The answer is rotation.
Step-by-step explanation:
A translation is a type of transformation, in which the original figure is just moved from its original place. It is not dilated or rotated, but just moved.
A rotation happens when the figure is rotated from a fixed point.
A dilation is a type of transformation that enlarges or reduces a figure.
A reflection is a transformation, where the mirror image is formed after transformation.
So, based on definitions, we can see that the given figure is rotated to get a new figure.
Therefore, the answer is rotation.
