Q.9 If \(\triangle ABC and \triangle PQR \) are to be congruent, name one additional pair of corresponding parts. What criterion did you use?


Answer :

In \(\triangle ABC and \triangle PQR \)
\(\angle ABC = \angle PQR \)
\(\angle BCA = \angle PRQ \)
The other additional pair of corresponding part is BC = QR
\(\therefore \triangle ABC \cong \triangle PQR \)
