Rotated at 90° clockwise about the origin. (RO 90)
Step-by-step explanation:
According to the statement A(–3, 4) maps to A'(4, 3), B(4, –5) maps to B'(–5, –4), and C(1, 6) maps to C'(6, –1). That is to say, that a point in the form P(x, y) maps to P(y, -x) after rotation.
In that sense, if a point P(x, y) maps to P(y, -x) then this happens when the shape denoted by those three points is rotated at 90° clockwise about the origin.
