On a coordinate plane, 3 triangles are shown. Triangle A B C has points (5, 2), (2, 4), (2, 1). Triangle A prime B prime C prime has points (negative 2, 5), (negative 4, 2), (negative 1, 2). Triangle A double-prime B double-prime C double-prime has points (negative 2, negative 5), (negative 4, negative 2), (negative 1, negative 2). Which rule describes the composition of transformations that maps ΔABC to ΔA"B"C"? 90 degree rotation about point 0 composition reflection across the x-axis Reflection across the x-axis composition 90 degree rotation about point 0 180 degree rotation about point 0 composition reflection across the x-axis Reflection across the x-axis composition 180 degree rotation about point 0
