Question

inthe given fig if pq=pt and TPS=QPR prove that PRS is isosceles

Answer 1

Angle TPS=QPR....1

ANGLE PRQ+PRS=180°....(ASP OF A TRIANGLE)

SLY,

ANGLE PST+PSR=180°

THEREFORE, ANGLE PRS=180-ANGLE PRQ

AND,

ANGLE PSR=180-ANGLE PRQ

THEREFORE, ANGLE PSR=ANGLE PRS

THEREFORE, TRIANGLE PSR IS ISOSCELES
