Question

2. Look at the figure, AD bisects 2A and AB =AC. By which property of
congruency is AABD AACD ? what concurrency is it?​

Answer 1

Answer:

In the given figure, If AD is the bisector of ∠A, then

∠BAD=∠CAD⇒BD=CD

And It is given, that AB=AC

∴∠B=∠C

Therefore △ABD and △ACD are congruent by ASA and SAS
