If a figure has been dilated by a scale factor of one third, which transformation could be used to prove the figures are similar using the AA similarity postulate? A translation because it can map one angle onto another since dilations preserve angle measures of triangles. A rotation because it can change the orientation of a figure since dilations do not preserve orientation. A dilation because it can map one side onto another since dilations preserve side length of triangles. A reflection because it can change the orientation of a figure since dilations do not preserve orientation.

A translation transformation could be used to prove the figures are similar using the AA similarity postulate because it can map one angle onto another since dilations preserve angle measures of triangles.

What is translation?

In a translation transformation, every point of the figure is moved by the same quantity. This means that the angles and lengths of the figure remain the same. The only thing that changes are the points on which it lies.

The transformation that could be used to prove the figures are similar using the AA similarity postulate is given below:

Translation transformation is the correct answer. This is because, in translation transformation, only the cartesian coordinates of the figure change. Nothing happens to the angles and lengths of the figure.

In the other given transformations, the orientations of the figures are not preserved and this makes it harder to prove using the AA similarity postulate.

Therefore, we have found that a translation transformation could be used to prove the figures are similar using the AA similarity postulate because it can map one angle onto another since dilations preserve angle measures of triangles.
