The figure shows ΔDEF and ΔD'E'F'. Fill in each entry box with the answer. Two triangles graphed on a coordinate plane. Triange D E F has vertices at D negative 2 comma negative 2, E 3 comma negative 2, and F 4 comma 3. Triangle D prime E prime F prime has vertices at D prime negative 4 comma 4, E prime 1 comma 4, and F prime 2 comma negative 1.

The glide reflection that maps ΔDEF onto ΔD'E'F' is T º Ry = 1 where a = and b = .
