Answer 2

Solution :

1 ) From the figure ( i ),

In ∆PQR and ∆UTS

PQ = UT ( S )

PR = US ( S )

QR = TS ( S )

Therefore,

∆PQR is congruent to ∆UTS

[ SSS criterion ]

2 ) From figure ( ii ) ,

In ∆ABD and ∆CBD

<ADB = <CDB ( A )

DB = BD ( common side )

<ABD = <CBD ( A )

Therefore ,

∆ABD is congruent to ∆CBD

[ ASA criterion ]
