(i) In ∆ABC and ∆PQR
AB = PQ= 1.5 cm
BC = QR = 2.5 cm
CA = RP = 2.2 cm
By S.S.S. condition of congruency ∆ABC ≅ ∆PQR
(ii) In ∆DEF and ∆LMN , EF ≠ MN
∴ These triangles are not congruent.
(iii) In ∆ABC and ∆PQR
BC ≠ QR
∴ These triangles are not congruent.
(iv) In ∆ADB and ∆ADC
AD = AD (common)
DB = DC = 2.5 cm
and BA = CA = 3.5 cm
In S.S.S. condition of congruency , ∆ADB ≅ ∆ADC.
