On a coordinate plane, 2 triangles are shown. The first triangle has points A (negative 2, 1), C (negative 4, 1), and B (negative 3, 4). The second triangle has points A prime (1, negative 2), B prime (4, negative 3), and C prime (1, negative 4).
A
ry=x(x, y) → (–y, –x)B
ry=–x(x, y) → (–y, –x)C
ry=x(x, y) → (y, x)D
ry=–x(x, y) → (y, x)3
