Which sequence of transformations does not preserve distance and angle? rotation and reflectiontranslation and reflectionrotation and dilation

Answer: rotation and dilation.

While rotation only rotates (obviously) the figure, dilation preserves the shape of the figure (that is, preserves the angles) but changes the distances: it makes the figure smaller.

The other 2 sequences of transformations only change the position of the figure, but the angles and distances remain intact.
