Given AB and CD are straight lines which intersect at O. OP is the bisector of ∠AO. To prove: OQ is the bisector of ∠BOD. Proof: AB, CD and PQ are straight lines which intersect in O. ∠AOP=∠BOQ(vertically opposite angles) ∠COP=∠DOQ(vertically opposite angles) ∠AOP=∠COP(OP is the bisector of ∠AOC) ∴∠BOQ=∠DOQ Thus, the rate opposite to the bisector of one of the angles thus formed bisects the vertically opposite angle. Similarly, the bisection of ∠AOD also bisects the ∠BOC.
