Question

2. In the following pairs of triangles, find out whether the triangles in each pair are congruendor
they are congruent, specify by which condition they become congruent.
(i) In AABC : AB = 4 cm, BC = 3 cm, ZB = 40"
In APOR: PO = 4 cm, OR = 3 cm, 20 = 40°
(ii) In AABC : AB = 6 cm, ZB = 50°, ZC = 90°
In ADEP: DE = 6 cm, ZE = 50°, ZF = 90°
(iii) In APQR : ZP = 60°, ZQ = 50°, ZR = 70°
In ALMN : L = 80°, ZN = 60°, ZM = 40°
3. In AABC and A PQR, BC = QR, ZA = 90°, ZB = 20 = 50° and ZR = 46°. IS AABC Z APOR
