The figure shows triangle PQR and some of its transformed images on a coordinate grid:

A coordinate plane is shown with five triangles. Triangle PQR has vertices 2 comma 1, 5 comma 1, and 2 comma 4. Triangle A has vertices negative 2 comma 1, negative 5 comma 1, and negative 5 comma 4. Triangle B has vertices negative 6 comma 1, negative 6 comma 4, and negative 9 comma 1. Triangle C has vertices negative 2 comma negative 1, negative 2 comma negative 4, negative 5 comma negative 4. Triangle D has vertices 2 comma negative 1, 5 comma negative 1, and 5 comma negative 4.
