(Preferably answered by tomorrow night - that's plenty of time.)
Ray OB is the bisector of angle AOC and ray OC is the bisector of angle BOD. m of angle AOC = 60. Find m of angle COD.
*m means "measure"
Write a proof in two-column form.
Given: ray DC is perpendicular to line BD; angle 1 is congruent to angle 2
Prove: ray BA is perpendicular to line BD
I have an image for the second problem, but they won't allow me to show links. ... )]= (Is there a remedy to this?)
Thank you guys <i>so much</i> in advance! =)

DC is perpendicular to BD. [Given]
Angle 2 = 90°. [Def. of perpendicular]
Angle 1 = angle 2. [Given]
Angle 1 = 90° [Transitive property of equality]
Therefore, BA is perpendicular to BD. [Def. of perpendicular]
