Which symbol is commonly used to denote the length of a segment?

• A. I
• B. L
• C. l
• D. Length

Answer: (C)

In geometry, the length of a segment is often denoted by a small letter, the lowercase l. It’s a simple, clear way to label the distance between the endpoints on a diagram, and you’ll see it used in many practice problems. While the length can also be written as the distance AB or with absolute value notation |AB| in more formal contexts, the lowercase l is a common shorthand in beginners’ work. The other symbols shown aren’t standard ways to represent the length of a segment. So the symbol you’d typically use for length is the lowercase l.
