Answer 1

Answer:

CDO ZOBA as it is very easy

Answer 2

Step-by-step explanation:

In triangles AOC and BOD, we have

AO = BO (O, the midpoint of AB);

∠AOC=

∠BOD

, (vertically opposite angles);

CO=

OD

, (O, the midpoint of CD)

So by SAS postulate we have

△AOC≅

△BOD

.

Hence, AC = BD, as they are corresponding parts of congruent triangles.

I hope my answer will help you,
