Select all the correct answers.Which two transformations preserve the side lengths and angles of the preimage? a reflection across line a stretch by a factor of 4 a dilation by a factor of 4 a translation to the right

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
