okay
here both triangles are equilateral triangle because all sides are equal then all angles will be 60°
and then PQS + RQS = 60 +60 = 120°
PQS = 120
they have td about angle pqr
why we have to tell about pqs
i have understood till 60 + 60 = 120

option (d) 120 degree
consider triangle PQS. all sides are equal so it is an equilateral triangle hence angle PQS = 60 degree
now by SSS criterion of congruency tiangle PQS is congruent to triangle RQS
hence angle PQR = 60+60= 120 degree
