TRIANGLE ABC is reflected about the line y = -x to give TRIANGLE A‘B‘C‘ with vertices
A‘(-1, 1), B‘(-2, -1), C(-1, 0). What are the vertices of TRIANGLE ABC?

• A(1, -1), B(-1, -2), C(0, -1)

• A(-1, 1), B(1, 2), C(0, 1)

• A(-1, -1), B(-2, -1), C(-1, 0)

• A(1, 1), B(2, -1), C(1, 0)

• A(1, 2), B(-1, 1), C(0, 1)
