Respuesta :

Which two transformations preserve the side lengths and angles of the preimage:

Rotations and reflections both preserve a polygon's side lengths. Dilations and translations both preserve a polygon's angle measures.

A reflection across line will preserve the angles

A dilation by a factor of 4 will preserve the both

Hence the correct answer is Option A and D
