Question

There are 4 Proof and statements that I need. Given AC=BD, and AB and CD bisect each other. Prove:

Answer 1

Given AC=BD.It is also said AB and CD bisect each other.

Since AB and CD bisect each other at O, we can write

AO=OB

CO=OD

Since the three sides of triangle AOC is equal to the corresponding sides of triangle BOD, both the traingles are congruent.

The angles opposite to equal sides of triangles are also equal.

Since AO and
