Question

In the figure, ∠BAD = ∠CAD and AD ⊥ BC. Prove that AB = AC.​

Answer 1

Answer:

It is defective to use ∠ABD=∠ACD for proving this result

It is defective to use ∠ABD=∠ACD for proving this result.

Step-by-step explanation:

△ABD and △ACD

AB=AC (given )

Then ∠ABD=∠ACD ( because AB=AC )

and ∠ADB=∠ADC=90( because AD⊥BC )

∴△ABD=△ACD

∠BAD=∠CAD
