GIVEN:-

  • AC = AE , AB = AD.

  • \rm{\angle{BAD} = \angle{EAC} }.

TO PROVE:-

  • BC = DE.

Now,

\implies\rm{\angle{BAD} = \angle{EAC}}.

  • \rm{\angle{DAC}} is a common, Adding it on Both sides.

\implies\rm{\angle{BAD} + \angle{DAC} = \angle{EAC} + \angle{DAC}}

\implies\rm{\angle{BAC} = {EAD}}......1.

Now, In ABC & ADE.

\implies\rm{AB = AD}(Given).

\implies\rm{AC = AE}(Given).

\implies\rm{\angle{BAC} = \angle{EAD}}.(From 1.).

Hence, \rm{\angle{ABC} ≈ \angle{ADE}} By S - A -S criteria.

So, BC = DE by CPCT.

EXTRA INFORMATION:-

  • S - S - S = When three side are equal to other corresponding triangle.

  • A - S - A -= When two angles and one Side is equal to other corresponding triangle.

Answer:

➡GIVEN:-

✏AC = AE , AB = AD.

✏∠BAD=∠EAC .

➡TO PROVE:-

✏BC = DE.

Now,

=>∠BAD=∠EAC .

⚫∠DAC is a common, Adding it on both sides.

=>∠BAD+∠DAC=∠EAC+∠DAC

=>∠BAC=EAD ......1.

⭐Now, In ∆ABC & ∆ADE.

➡ Given:-

✏AB=AD

✏AC=AE

=>∠BAC=∠EAD .(From 1.).

Hence, ∠ABC≈∠ADE

(By S - A -S criteria.)

So, BC = DE by CPCT.
