Question

In the given figure, if $OA=OB,OD=OC$, then $\Delta AOD\cong \Delta BOC$ by congruence rule :

• A. SSS
• B. ASA
• C. SAS
• D. RHS

Answer 1

Answer: (C)

SAS

In $△AOD$ and $△BOC$

$AO=BO$ (given)

$OD=OC$ (given)

$\angle AOD=\angle BOC$ (vertically opposite angle )

$△AOD\cong △BOC$ by $SAS$ congruence rule.

ΔAOD≅ΔBOC
