2: DOC = AOB 2: Vertical angles are equal.

3: Triangle COD congruent to Triangle AOB 3: SAS

4: 1 = 2, AB = DC 4: CPCTE

5: AB||DC 5: If alternate interior angles =, then lines parallel.

6: ABABCD is a parallelogram 6: If two sides = and ||, then a parallelogram.

I just had this question on my lesson, the answers are right! Goodluck! :)
