PCQ and ACP are supplementary by the Linear Pair Theorem.

For parallel lines cut by a transversal, corresponding angles are congruent, so ACB PCQ.

OCP BCD by the Vertical Angles Theorem.

For parallel lines cut by a transversal, corresponding angles are congruent, so OCP ABC.

For parallel lines cut by a transversal, corresponding angles are congruent, so OCA CBD.
