Question

$\text{If}△ABC\text{and}△PQR$ are to be congruent, name one additional pair of corresponding parts. What criterion did you use?

Answer 1

By observing the given figure, we can say that
$\angle ABC=\angle PQR$
$\angle BCA=\angle QRP$
(0.5 mark)
The other additional pair of corresponding part should be
BC = QR
(0.5 mark)
Hence, from ASA Congruence criterion,
$\therefore △ABC\cong △PQR$
(1 mark)

Also, if AC = PR, then these two triangles would be congruent by AAS congruence rule.
