abcd is a rectangle. trapezoid aefb is congruent to trapezoid cfed.
g is the mid - point of segment ef.
describe the rigid transformation that takes aefb to cfed.
rotate aefb degrees counterclockwise around point

Explanation:

Step1: Analyze congruent trapezoids

Since trapezoid \(AEFB\) is congruent to trapezoid \(CFED\) and we want to map \(AEFB\) to \(CFED\), and \(G\) is the mid - point of \(EF\).

Step2: Determine rotation

The transformation that maps one trapezoid to the other is a rotation. The center of rotation is the mid - point \(G\) of the common side \(EF\), and the angle of rotation is \(180\) degrees counter - clockwise to make the corresponding parts of the congruent trapezoids match.

Answer:

180, G
