2.2. Triangle ABC shown below is reflected over the line y = 1 to obtain triangle A'B'C'. What sequence of transformations would also map triangle ABC onto triangle A'B'C'?
B
I
A. a reflection over the x-axis followed by a translation down 2 units
B. a reflection over the y-axis followed by a reflection over the line x = 1.
C. a rotation of 180° about the origin, then a reflection over the x-axis, and then a translation
left 2 units
D. a rotation of 1800 about the origin, then a reflection over the y -axis, and then a translation
up 2 units
