Answer:

B'C'D'

Step-by-step explanation:

The figure was just translated, without any deformation, these are similar figures... so their corresponding angles are the same.

Since it was just moved down by 4 units, none of the angles were changed, and none of the side lengths were changed.

Since vertex C' corresponds to vertex C, the angle B'C'D' corresponds to original angle BCD.
