Answer:
Sides opposite to equal angles are always equal.
Consider triangle ABC, with ∠ABC=∠ACB
AD is a median from A on BC such that, BD=CD
Now in △ABD and △ACD
∠ABD=∠ACD (Given)
BD=CD (From Construction)
AD=AD (Common side)
Thus, △ABD=△ACD (SAS rule)
Hence, AB=AC
or sides opposite equal angles are equal.
