2-6.

The diagrams below are not necessarily drawn to scale. For each pair of triangles:

Determine if the two triangles are congruent.

If the triangles are congruent, write a congruence statement (such as

) and give the congruence theorem (such as ). If the triangles are not congruent, or if there is not enough information to determine congruence, write “cannot be determined” and explain why not.

A shared side is a congruent side.

AAA does not prove congruency.

Order matters: SAS proves congruence but SSA does not.

is a straight segment:
