Answer:
C. They can be parts of lines.
D. They connect two endpoints.
Step-by-step explanation:
A line segment is nothing more than a part of a line that has a starting point and an end point, called "extremes." Two line segments connect two endpoints.
According to their position, the straight segments can be classified into consecutive segments, collinear segments or adjacent segments. If two segments of lines are parallel, they will not be classified according to any of these three types of segments.
