What single transformation was applied to quadrilateral A to get Quadrilateral B?

Answer:
Rotation because it is the right answer due to dialations changing size and reflections and translations would not change the way the shape is oriented.
Answer:
Most Likely A Rotation
Step-by-step explanation:
The two shapes look the same size, so it would not have been dilated.
A reflection would have the shapes "reflected". The shapes are not reflected.
But, the shape has most likely been rotated, since the two shapes are in different positions of rotation.
