s Find ZOPQ and ZROS.In the figure PR and QS are two diameters. Is PQ

1.	s Find ZOPQ and ZROS.In the figure PR and QS are two diameters. Is PQ RS?
Answer» As PR and QS are diameter PR = QSSo, PO = OR ....(1)OQ = SO ......(2) Now in ∆POQ and ∆ SORPO = OR .... by (1) OQ = SO .... by (2) angle POQ = angle SOR ( vertically opposite angle) By SAS rule ∆POQ and ∆ SOR are congurent so by CPCT PQ = SR. Yes

Answer»

As PR and QS are diameter

PR = QSSo, PO = OR ....(1)OQ = SO ......(2)

Now in ∆POQ and ∆ SORPO = OR .... by (1)

OQ = SO .... by (2)

angle POQ = angle SOR ( vertically opposite angle)

By SAS rule ∆POQ and ∆ SOR are congurent so by CPCT PQ = SR.

Yes
