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 180 (dagree) rotation about the origin a 90 (dagree) counterclockwise rotation about the origin and a translation down 4 units a 90 (dagree) clockwise rotation about the origin and a reflection over the y-axis a reflection over the y-axis and then a 90(dagree) clockwise rotation about the origin
