it's a correct answer of this given figure

kanishkapal700: i am not able to infer

kanishkapal700: *understand

navya9032: okay

navya9032: here both triangles are equilateral triangle because all sides are equal then all angles will be 60°

navya9032: and then PQS + RQS = 60 +60 = 120°

navya9032: PQS = 120

kanishkapal700: they have td about angle pqr

kanishkapal700: why we have to tell about pqs

kanishkapal700: i have understood till 60 + 60 = 120

navya9032: ok

Answered by anjishnusaw91

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

pls pls mark me as the brainliest and do follow mw all pls
