Line segment: 1 Mark
Ray: 1 Mark
Number of Lines segments: 1 Mark
In a line segment, the endpoints are fixed i.e. a line is contained between two points.
A ray is a portion of a line. It starts at one point and goes endlessly in one direction.
The line segments in the above figure are:
AB,AC,AD,AE,BC,BD,BE,CD,CE,DE.
Hence there 10 lines segments in the above figure.
