Given : \triangle ABE \cong \triangle ACD

To prove ADE ~ \Delta ABC.

Since \triangle ABE \cong \triangle ACD

      AB=AC          ( By CPCT)

      AD=AE          (By CPCT)

In \DeltaADE  and  \Delta ABC,

     \angle A=\angle A    ( Common)

and    

              \frac{AD}{AB}=\frac{AE}{AC}       (  AB=AC   and   AD=AE )

Therefore, \DeltaADE ~ \Delta ABC.   ( By SAS criteria)
