Question

identify the transformation shown on the coordinate plane. * translation reflection rotation

Explanation:

The two trapezoids are mirror images across the x-axis, where each point of the top shape maps to a point directly below/above it on the bottom shape with the same x-coordinate and opposite y-coordinate. This matches the definition of a reflection over a line (the x-axis here). Translation would shift the shape without flipping, and rotation would turn it around a point, neither of which is shown.

Answer:

reflection
