in triangleABC, D and E are points on C such that AD = AE and BD = CE, prove that AB=AC​

Answer 1

Answerin triangleABC, D and E are points on C such that AD = AE and BD = CE, prove that AB=AC​

Step-by-step explanation:

Answer 2

Answer:Given,

AD=AE  where, D and E are points on BC,

Such that BD = EC,

To prove :

AB = AC,

Proof :

∵ AD=AE

⇒ ∠ADE = ∠AED

⇒ 180° -  ∠ADE =  180° -  ∠AED

⇒ ∠ADB = ∠AEC,

BD = EC ( given )

By SAS postulate of congruence,

Δ ABD ≅ Δ ACE

By CPCT,

AB = AC

Hence, proved.....
