Answer 1

Draw a line Joining DE

given

AB=AD

AC=AE

angle BAD=angle CAE

Also let us take angle DAC as X

In Triangle ABC And ADE

AB=AD

AC=AE

Angle BAC=Angle BAD + X

Angle DAE = angle CAE + X

But angle BAD = angle CAE

So angle BAC=angle DAE

FROM SAS criteria triangle ABC and Triangle ADE are congruent

hence BC=DE

Sorry if I haven't explained properly... it's been a long time since I have done prove the triangle.

Hope this helps
