There are 4 proofs and statements please give them. If you aren't sure please don't answer. Given AC=BD, and AB and CD bisect each other. Prove: <A= <B

Step-by-step explanation:
Given: O is mid point of AB and CD
∴ AO=OB and CO=OD
To prove: AC=BD
Proof: Consider △AOC and △BOD
AO=OB (given)
CO=OD (Given)
∠AOC=∠BOD (Vertically Opposite angle)
△AOC≡△BOD
Hece we get, AC=BD (by c.p.c.t.)
