An [b]inscribed angle [/b]is an angle formed by two chords in a circle which have a common endpoint. This common endpoint forms the [i]vertex - C - [/i]of the inscribed angle. The other two endpoints - B and D - define what we call an [b]intercepted arc [/b]on the circle. ... The [i]minor arc [/i]is the smaller of the two arcs (arc BD) while the [i]major arc [/i]is the bigger (arc BCD).
