Question

By applying $SAS$ congruence rule, you want to establish that $\Delta PQR\cong \Delta FED.$ It is given that $PQ=FE\text{and}RP=DF.$ What additional information is needed to establish the congruence ?

Answer 1

Since for $\Delta PQR\cong \Delta FED$

Given $PQ=FE,RP=DF$ then the additional required information will be the angle included

Additional information is required that $\angle QPR$must be equal to $\angle EFD$
