Question

ABC is an isosceles triangle in which AD BC Prove that BAD = CAD


wrong ans will be reported


​

Answer 1

Answer:

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

△ABD and △ACD

AB=AC (given )

Then ∠ABD=∠ACD ( because AB=AC )

and ∠ADB=∠ADC=90( because AD⊥BC )

∴△ABD=△ACD

∠BAD=∠CAD

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