SAS criterion: If two sides and the included angle of one triangle are equal to the corresponding sides and angle of another triangle, the triangles are congruent.
From the diagram you can see that
[tex] \angle A\cong \angle F\cong \angle P,\\AB\cong GF\cong PQ,\\AC\cong FE\cong PR. [/tex]
This means that ΔABC, ΔFGE and ΔPQR are congruent, so last option is correct.
