Question

In the given figure​

Answer 1

Given,

AC=AE

AB=AD

Angle BAD= Angle EAC

Now take 2 triangles --- Triangle ABD and Triangle ADE

angle BAD+Angle DAC=angle DAC+ angle EAC (because angle DAC is common)

Therefore both the triangles are congruent by SAS criterion.

Therefore BC=DE (by CPCT).
