1. It is given that \(\triangle ABC \cong \triangle RPQ\). Is it true to say that \(BC = QR\)? Why?
 
2. If \(\triangle PQR \cong \triangle EDF\), then is it true to say that \(PR = EF\)? Give reason for your answer.
 
Answer :
 
1. Let us consider ,By the SSS congruence rule, we have:
 
\(AB =\), \(BC =\) and \(AC =\).
 
Thus, it is  to say that \(BC = QR\).
