what else do you need to know to prove that they are congruent and which postulate are you using to prove their congruence?

The triangles PQR and FGH

We know that the corresponding angles

∠P=∠F

∠Q=∠G

> For the congruence postulate of Angle-Side-Angle to apply, the sides between them should be congruent to, that is:


PQ=FG

>For the congruence postulate of Angle-Angle-Angle to apply, the third angle of each triangle must be corresponding and congruent as well


\angle R=\angle H

> For the postulate Angle-Angle-Side to apply, two corresponding angle pairs must be congruent and two corresponding sides that are not between them must be congruent too, for example:


QR=GH

-or


PR=FH

>For the postulate Side-Side-Side to apply, all corresponding sides must be equal


\begin{gathered} PQ=FG \\ QR=GH \\ PR=FH \end{gathered}
