Triangle QRS is transformed as shown on the graph.
On a coordinate plane, 2 triangles are shown. The first triangle has points Q (2, negative 1), R (5, negative 2), S (4, 1). The second triangle has points Q prime (negative 1, negative 2), R prime (negative 2, negative 5), S prime (1, negative 4).
Which rule describes the transformation?
R0, 90°
R0, 180°
R0, 270°
R0, 360

R0, 270°.
Reason: A 270° rotation about the origin sends (x,y) to (y,−x).
Q(2,−1) -> (−1,−2), R(5,−2) -> (−2,−5), S(4,1) -> (1,−4), which match Q', R', S'.
