In the given figure, seg AB is a diameter of a circle with centre O. The bisector of ∠ACB intersects the circle at point D. Prove that, seg AD ≅ seg BD.
Complete the following proof by filling in the blanks.

Proof: Draw seg OD.

∠ACB = ______      ...(Angle inscribed in semicircle)
∠DCB = ______      ...(CD is the bisector of ∠C)
m(arc DB) = ______   ...(Inscribed angle theorem)
∠DOB = ______      ...(Definition of measure of an arc)(I)
