Angles, chords and arcs
Does anyone know of any good sites where I can learn about chords, arcs and angles? I am interested in all or at least most of the rules followed when applying these, anyone know where I can find out?
EDIT: I think I will be having an exam in two weeks that will have questions involving these, so if anyone wants to help just any info, big or small will be helpful whether or not I am aware of them. Or if anyone knows, could they please state the rules used in your reply and I will try to make sense of them as soon as I can.

Are you studying things such as "What is the measure of a a tangent line and its intercepted arc" kind of thing?
