If in $\triangle ABC$ and $\triangle DEF$, $AB = DE$, $\angle B = \angle E$, and $BC = EF$, which rule proves $\triangle ABC \cong \triangle DEF$?
- SSS
- SAS
- ASA
- RHS
Correct answer: SAS
Solution
The triangles have two corresponding sides equal, $AB=DE$ and $BC=EF$, and the included angle between them is also equal, $\angle B=\angle E$. Therefore, the congruence criterion is SAS.
