Which postulate, if any, can be used to prove the triangles congruent?
Two vertices that are the endpoints of a side are called consecutive vertices.
For example, P and Q are consecutive vertices.
To name a polygon, write the vertices in consecutive order. For example, you can name polygon PQRS as QRSP or SRQP, but not as PRQS.
In a congruence statement, the order of the vertices indicates the corresponding parts.
When you write a statement such as ABCDEF, you are also stating which parts are congruent.
< BAC _______
If two angles and a non-included side of one triangle are congruent to two angles and a non-included side of another triangle then the triangles are congruent.
