Question

identify the transformation. is this a reflection, translation, or rotation?
rotation
reflection
translation

Explanation:

The two purple shapes are mirror images across the vertical line between them. A reflection transformation creates a mirror - like image over a line (the axis of reflection), which matches the relationship between these two shapes. Rotation would involve turning a shape around a point, and translation would involve sliding a shape without rotating or reflecting it, so the transformation here is a reflection.

Answer:

B. reflection
