Use the image to answer the question.

Two triangles, upper A upper B upper C and upper D upper E upper F, are graphed on a coordinate plane. The x-axis ranges from negative 5 to 6 in increments of 1. The y-axis ranges from negative 3 to 5 in increments of 1.

Determine the congruence transformation used on △ABC that resulted in △DEF.
