Hey all. At my school we have these things called "Real Problems" that we get every 3-4 weeks. This time it's about proofs. I have an A- in the class, so I got the difficult one with 4 very difficult (IMO) proofs.
I have NO idea where to start on this..I have drawn it out for you. All help is greatly appreciated. I am here to merely learn, not copy everything. I would appreciate full answers, but I am definitely here to Learn how to do this for tests.
Given: Tangent line AB and chord BC.
Prove: <ABC = (1/2)(arc)BC
In other words prove: (Angle ABC = Half of arc BC)
HINT: Using the center of the circle, draw in OB and OC (which I did in the picture for you).
