Each of the figures should be classified as a line, ray, or line segment as follows;
a. Line segment ↔ line segment AB.
b. Line ↔ line CD.
c. Ray ↔ ray FE.
In Mathematics and Euclidean geometry, a line is a mark with length and direction, that is created by a point that is moving across a surface and extending infinitely such as line CD.
A line segment is the part of a line in a geometric figure that is bounded by two distinct points. This ultimately implies that, a line segment typically has a fixed length such as line segment AB.
A ray is composed of two points that are joined by a straight line and it extends infinitely in a single direction such as ray FE.
