Angles that share a side and a vertex but do not overlap
What are adjacent angles?
200
When you have two corresponding angles with a corresponding side between them
What is ASA?
200
Look at Figure #2. Are these two triangles congruent? If so, state the congruence statement and the postulate you used to get your answer. If they're not, put not congruent.

When you have two corresponding angles and a corresponding side that is not included between these angles
What is AAS?
300
Look at Figure #3. Are these two triangles congruent? If so, state the congruence statement and the postulate you used to get your answer. If they're not, put not congruent.
What is not congruent?

400
When you have two corresponding sides and a corresponding angle between them
What is SAS?
