Question

INDIRECT PROOF

Answer 1

Given: BC//AD & triangle ABC is not isosceles
Proof: AC does not bicect <BAD

Answer 2

to do indirect proof, you must assume the negation of the conclusion is true.

the negation of what you need to prove is : AC bisects <BAD.
this should lead to a contradiction of the given...

Answer 3

what's the contradiction?

Answer 4

That's what I need help with I can't find any more statements or reasons to prove the triangles are congruent & do a CPCTC for my contradiction.
