1. AAA criteria of triangle they are congruent 2.angle x = angle y angle AOP=angle BOR. vertical angle therefore side AP=BR since, ASA criterion triangle AOP & Triangle BOR are equal & congruent therefore AO=OR & BO=OP also angle AOB=angle POR. vertical angle therefore OA = OB =OP =OR hence AR =PB

2.angle x = angle y
angle AOP=angle BOR. vertical angle
therefore side AP=BR
since, ASA criterion triangle AOP & Triangle BOR are equal & congruent
therefore
AO=OR
&
BO=OP
also
angle AOB=angle POR. vertical angle
therefore
OA = OB =OP =OR
hence
AR =PB
