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
