Trapezoid E F G H is reflected across line of reflection k to form trapezoid E prime F prime G prime H prime. Trapezoid E prime F prime G prime H prime is shifted down to E double-prime F double-prime G double-prime H double-prime. Which composition of transformations maps figure EFGH to figure E"F"G"H"? a reflection across line k followed by a translation down a translation down followed by a reflection across line k a 180° rotation about point G followed by a translation to the right a translation to the right followed by a 180° rotation about point G
