Solution

The correct option is B ASA
In triangle PQR,
P=60°
Q=55°

We know that, sum of internal angles of a triangle is 180°

So,
R=180°(P+Q)
R=180°(60°+55°)
R=65° .....(1)



In ABC and PQR,
B=Q=55°
BC = QR = 5cm... (given)
C=R=65° .... (from 1)

So, by ASA criterion for congruency of triangles,
ABCPQR
