(2) BC = CD

Hi,
I get kind of lost with the properties of perpendicular bisector. When I see a perpendicular bisector, I don't know what it means, except that there are two 90 degree angles formed.
Why is statement A not sufficient?
Statement A says it is a perpendicular bisector. Therefore there is a 90 degree angle, and the right angle BAD is cut 90/2 degrees, which is 45 degrees right? Forming a 45-45-90 angle, you can get length BD.
Can you explain to me why statement A is insufficient?
EDIT: Is there a diff between perpendicular vs perpendicular bisector? IS there such a thing as only bisector? :( What are the difference among the 3?
Thanks.
