This is gibberish; please be more careful how the questions look before posting. Anyway, I'll guess it says
Given OB bisects ∠AOC and OC bisects ∠BOD prove m∠AOB = m∠COD
Proof:
Statements Reasons
OB bisects ∠AOC Given
m∠AOB = m∠BOC = (1/2) m∠AOC Definition of angle bisector
OC bisects ∠BOD Given
m∠BOC = m∠COD = (1/2) m∠BOD Definition of angle bisector
m∠AOB = m∠COD transitivity of equality
