Which transformations can be used to map a triangle with vertices A (2, 2), B (4, 1), C (4, 5) to A' (-2, - 2), B' (-1, - 4), C' (-5, - 4) ?

a

a 90 degree clockwise rotation about the origin and a reflection over the y-axis

b

a 90 degree counterclockwise rotation about the origin and a translation down 4 units

c

a 180 degree rotation about the origin

d

a reflection over the y-axis and then a 90 degree clockwise rotation about the origin
