If a figure has been dilated by a scale factor of 1/3, which transformation could be used to prove the figures are similar using the aa similarity postulate?

a) a translation because it can map one angle onto another since dilations preserve angle measures of triangles.
b) a rotation because it can change the orientation of a figure since dilations do not preserve orientation.
c) a dilation because it can map one side onto another since dilations preserve side length of triangles.
d) a reflection because it can change the orientation of a figure since dilations do not preserve orientation.
