Explanation:

Step1: Recall dilation properties

Dilation preserves orientation, changes size.

Step2: Evaluate first statement

Orientation stays same in dilation. So this is true.

Step3: Evaluate second statement

Congruent figures have equal size. Scale factor ≠1 changes size, so they are not congruent. This is false.

Answer:

The orientation of the figure did not change. $\boldsymbol{\checkmark}$ (True)
The pre-image and image are congruent figures. $\boldsymbol{\times}$ (False)
