In ΔABC, an angle bisector from A meets BC at D. If AD bisects ∠BAC, and AB = AC, are ΔABD and ΔACD congruent? If so, by what rule?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. Yes, by SAS.
In ΔABD and ΔACD,
AB = AC
AD = Common side
∠BAD = ∠CAD
ΔABD ≅ ΔACD by SAS
