[/_XYQ" and reflex "/_QYP.],[" 7.If OP bisects "/_BOC" and "OQ/_AOC," show that "/_POQ=90^(@)." In the "],[" given Fig."6.19]

In Figure,OP bisects /_BOC and OQ,/_AOC .Show that /_POQ=90^(@)

In Fig.9, if ray OC stands on line AB such that /_AOC=/_COB, then show that /_AOC=90^(@).

In figure, OP bisects angle BOC and OQ bisects angle AOC , then angle POQ is

In the given figure, if OP bisects angleBOC and OQ bisects angleAOC , then anglePOQ is equal to

In figure,AB and CD are straight lines and OP and OQ are respectively the bisetors of angles /_BOD and /_AOC. Show that the rays OP and OQ are in the same line.

In the given figure Q is a point inside /_PQR such that /_PQR=90^(@),OP=6cm and QR=26cm then what is /_PQR

In Fig. 7.15, DE abs() OQ and Dfabs()OR ,Show that Efabs()QR.

In Fig. 7.8, OA = OB and OD = OC. Show that (i) Delta AOD cong Delta BOC and (ii) AD || BC.

In Fig. 6.20, DE||OQ and DF||OR .Show that EF||QR .
