When writing the name of a segment, it is common to use two capital letters with a line segment symbol above them. This symbol resembles a small arrow pointing to the right. For example, a segment name could be written as AB with the symbol above it. In contrast, when writing the name of a line, one often uses a single lowercase letter with a line symbol drawn above it. This line symbol extends above both the letter and the line. For instance, a line name could be written as l with the line symbol above it.
When writing the name of a segment, it is common to use a single lowercase letter to represent the two endpoints of the segment, such as "AB". On the other hand, when writing the name of a line, a single lowercase letter is often used to represent any point on the line, such as "l". To distinguish between the two, some symbols can be used. For example, a line may be denoted as "line l" or "l", while a segment can be denoted as "segment AB" or "AB". These symbols help to indicate the nature of the geometric entity being referred to.
