Question

$ΔABD$ and $ΔECD$ are congruent

Open in App

Verified by Toppr

AD is produce to E so that DE = AD

We need to prove that

$ΔABD≅ΔECD$

AB = EC

AB \\ EC

In $ΔABD$ and $ΔECD$

BD = DE [D is the midpoint of BC]

$∠ADB=∠CDE$ [Vertically opposite angles]

AD = DE [Given]

By Side - Angle - Side criterion of congruence we have

$ΔABD≅ΔECD$
