Step-by-step explanation:

  • <QTS
  • <BCD
  • <QPO and <ORS
  • <EFG
  • <ACF and <CFE
  • <BED
  • <TUY
  • <ABC+<BCD=180° (being co-interior angles)

1. ∠STQ

2. ∠BCD

3. ∠ORS and ∠QPO both are alternate angles of ∠POR

4. ∠EFG

5. ∠DCF and ∠CFH

6. ∠DEB

7. ∠YUT

8. 180° (because they are co-interior angles)
