A composition of transformations maps pre-image EFGH to final image E"F"G"H". Trapezoid E F G H is shifted down and to the left to trapezoid E prime F prime G prime H prime. Trapezoid E prime F prime G prime H prime is reflected across the line of reflection c to form trapezoid E double-prime F double-prime G double-prime H double-prime.

The first transformation for this composition is [], and the second transformation is a reflection across line c.
