Answer:
1. ABCD is a parallelogram 1. Given
2. AB || CD 2. def. of parallelogram
3. BC || DA 3. def. of parallelogram
4. draw AC 4. unique line postulate
5. <BCA and <DAC are alt. interior angles 5. def. of alt. interior angles
6.DCA and <BAC are alt interior angles 6. def. of alt. interior angles
7.<BAC = DCA 7. alternate interior angles theorem
8. <BCA = DAC 8.alternate interior angles theorem
9. AC = AC 9. Reflexive property
10. (triangle) ABC = CDA 10. ASA
11. AB = CD 11. CPCTC
12. BC = DA 11. CPCTC
