Question

prove that angle PRQ and PSQ= 180​

Answer 1

Answer:

angle PRQ

In angle PRQ

PR = RQ

RQ = QP

In angle PSQ

PS = SQ

SQ = PQ

Answer 2

Angle RPQ= Angle PSR.......(1)

Angle RQP= Angle RSQ....... (2)

In triangle PRQ,

Angle PRQ + angle RPQ + angle RQP =180

So angle PRQ + angle PSR +angle RSQ =180....from (1) & (2)

Angle PRQ + angle PSQ = 180...(angle addition property)
