Answer:
Since
AB = PQ
BC = QR
CA = PR
So, by SSS congruency rule both triangles are congruent to each other.
\Delta ABC \cong\Delta PQR
ii) Since,
ED = MN
DF = NL
FE = LM
So, by SSS congruency rule both triangles are congruent to each other.
\Delta EDF\cong\Delta MNL.
iii) Since
AC = PR
BC = QR But
AB\neq QR
So the given triangles are not congruent.
iv) Since,
AD = AD
AB = AC
BD = CD
So, By SSS Congruency rule, they both are congruent to each other.
\Delta ADB\cong\Delta ADC.
