Answer:
1. m∠2 = 180 - 72 = 108° (supplementary)
2. m∠3 = m∠1 = 72° (vertical angles)
3. m∠4 = m∠2 = 108° (vertical angles)
4. m∠5 = m∠1 = 72° (corresponding angles)
5. m∠6 = m∠2 = 108° (corresponding angles)
6. m∠7 = m∠1 = 72° (alternate exterior angles)
7. m∠8 = m∠2 = 108° (alternate exterior angles)
8. m∠1 = 180 - 78 = 102° (co-exterior angles)
9. m∠2 = m∠8 = 78° (alternate exterior angles)
10. m∠3 = m∠1 = 102° (vertical angles)
11. m∠4 = m∠2 = 78° (vertical angles)
12. m∠5 = m∠1 = 102° (corresponding angles)
13. m∠6 = m∠2 = 78° (corresponding angles)
14. m∠7 = m∠1 = 102° (alternate exterior angles)
