A circular swimming pool consists of a straight rope connecting 2 points on the boundary of the pool. What will the region between the rope and the boundary be called?
Segment
The region enclosed between the rope and boundary has been clearly indicated in yellow colour. The portion of the circular region enclosed between a chord and the corresponding arc is called a segment. The rope here is the chord. The corresponding arc is the boundary of the swimming pool for the yellow region. Hence the enclosed region is a segment.
