Question

13. Which of the following pairs of
triangles are congruent ? State reason also:
I)
In triangleABC: AB = 2 cm,
BC = 3 cm, angleB = 30°
In trianglePQR : PQ = 2 cm,
QR = 3 cm, angleQ = 30°

ii) In triangleABC: AB = 4 cm, BC = 5 cm.
angleA = 50°
In trianglePQR : PQ = 4 cm,
QR = 5 cm, angleP = 50°

iii) In triangleABC : AB = 5 cm.
BC = 7 cm, angleC = 40
In tranglePQR : PQ = 5 cm,
QR = 7 cm, angleR = 40

iv) In triangleABC: angleB = 60°,
angleC = 70°, BC = 4 cm
In ttianglePQR: angleQ = 60°
angleR = 70°. QR = 4 cm

v) In triangleABC : AC = 13 cm,
angleB = 90° AB = 5 cm
In triangle PQR : PR = 13 cm.
angleQ = 90°, PQ = 5 cm

vi) In A ABC : AB = 5 cm,
BC 4 cm, CA = 6 cm
In trianglePQR : PQ = 5 cm,
QR = 4 cm, RP = 6 cm.​
