Nora says that the shapes shown below are translations of each other. Nora is correct because the image has just moved to a different set of (x, y)s, while its shape maintained the same directionality of its positioning (the parts of the arrow).
Judy is incorrect in calling it a glide-reflection; such requires a movement (translation), followed by a flip (reflection) across either the x- or y-axis.
Considering that the point and base of the "arrow" image has not changed or flipped in the movement, no reflection had occurred.
