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 180 degree rotation about the origin b)a 90 degree counterclockwise rotation about the origin and a translation down 4 units c)a 90 degree clockwise rotation about the origin and a reflection over the y-axis d)a reflection over the y-axis and then a 90 degree clockwise rotation about the origin
