MR. Organic Chemistry Tutor, thank you for great video on Two Column Proofs With Circles in Plane/Solid Geometry. I am really getting a full understanding of Two Columns Proofs in all of Geometry.

The statement 4 at 6:50 is incorrect. BD doesn't have to be perpendicular to AC to bisect AC, as chord AC is a diameter in this case.

I agree. I was thinking in terms of this statement: If a diameter or radius is perpendicular to a chord, then it bisects the chord and its arc. Nevertheless, chord AC is a diameter since B is the center of the circle so automatically AB must be congruent with BC regardless if BD is perpendicular to AC or not. Thanks for bringing this to my attention.

Why can't there actually write out the whole reason? Just like how smart people just assume you know what they're are talking about.

Can you also state that Ab and Cb are tangents because they form a right angle at a point on the circle and if two tangents meet up at the same exterior point then the lines are +?

In a geometry EOC, does the order of the statements and reasons matter?
