Answer:
2. Not enough information
4. Congruent SAS
4. Similar, not enough information to determine congruency.
Step-by-step explanation:
2. We only know one side and one angle are congruent, Not enough to determine congruency
4. We know two sides and the angle between are vertical angles and vertical angles are congruent. SAS is how the triangles are congruent.
6. The three angles are congruent which makes the triangles similar. We need to know a side if they are to be congruent
