The AAS theorem, tells us that two angles of any side of the triangle are said to be congruent to the two angles of another triangle then ae congruent. Therefore:
[tex]\begin{gathered} \angle H\cong\angle R \\ \angle G\cong\angle S \\ FH\cong RT \end{gathered}[/tex]
So, the triangles GHF and SRT are congruent.
Answer:
[tex]\Delta GHF\cong\Delta SRT[/tex]
