Answer:
Both lines segments are congruent.
Explanation:
There are a couple of key facts here.
The first key fact is the description. It states that Lucia constructed CD as a COPY of AB. We can already tell that the line segments will most likely be congruent and exactly the same if she did it right.
The next key fact is the picture given. We can see that segment AB and segment CD both have the 2 tiny lines in them. This means that AB = CD.
So, given this, we can say that AB and CD are congruent.
Hope this helps! :)
