Since triangle ABC was dilated, The side lengths were multiplied by a scale factor, preserving the angle measures.

A dilation is a transformation that produces an image that is the same shape as the original but is a different size, It can stretch or shrink a figure. In other words, it changes the side lengths but keeps the angle measures.

Option 1 is correct but is lacking information about angles.

Option 3 is wrong, side lengths were not preserved.

Option 4 is wrong, side lengths were not preserved.

Correct option:

The side lengths were multiplied by XY/AB, while the angle measures were preserved.
