a transformation of △def results in △def. which transformation maps the pre - image to the image? the…

Explanation:

Step1: Analyze dilation

Dilation changes the size of a figure. The pre - image and image here have the same size, so it's not a dilation.

Step2: Analyze reflection

Reflection flips a figure over a line. There is no indication of a flip here.

Step3: Analyze rotation

Rotation turns a figure around a point. The orientation of the triangle has changed, which is characteristic of a rotation.

Step4: Analyze translation

Translation moves a figure without changing its orientation. The orientation has changed, so it's not a translation.

Answer:

The transformation is a rotation.
