Question

choose 1 answer: a translation b rotation c reflection d dilation

Explanation:

Step1: Analyze translation

Translation is moving a figure without rotation or reflection. But here the orientation of the figure has changed, so it's not translation.

Step2: Analyze reflection

Reflection flips a figure over a line. The orientation change here is not due to a simple flip.

Step3: Analyze dilation

Dilation changes the size of a figure. The size of figure A and B seems the same, so it's not dilation.

Step4: Analyze rotation

Rotation turns a figure around a point. The change in orientation of figure A to B is consistent with rotation.

Answer:

B. Rotation
