A segment of a circle is the figure contained by a straight line and a circumference of a circle.
A segment of a circle is a figure bounded by a chord and an arc of a circle, whose endpoints are the endpoints of the chord.
Please note that each chord generates two segments, because there are two arcs whose endpoints are the endpoints of the chord. Which segment is meant, shall be made clear from the context.
