Answer:
1. possibly congruent
2. possibly congruent
3. congruent
4. similar
Explanation:
It is impossible to tell for the first two. In order to be congruent they must have the measurements (lengthes& angles) for all coordinating sides and angles. Since we don't have that info we can only guess and since the look exactly the same we can guess they are congruent.
The third one being on the graph we can tell these are congruent.
the fourth one is obviously not congruent because the side lengths are different. We are guesing that the coordinating angles are congruent
