Q.1 Which congruence criterion do you use in the following?
(a) Given:
AC = DF
AB = DE
BC = EF
So, \(\triangle ABC \cong \triangle DEF \)


(b) Given:
ZX = RP
RQ = ZY
\(\angle PRQ = \angle XZY \)
So, \(\triangle PQR \cong \triangle XYZ \)


(c) Given: \(\angle MLN = \angle FGH \)
\(\angle NML = \angle GFH \)
ML = FG
So, \(\triangle LMN \cong \triangle GFH \)

(d) Given: EB = DB
AE = BC
\(\angle A = \angle C = 90° \)
So, \(\triangle ABE \cong \triangle CDB \)
