Symbol. The parallel symbol is . For example, indicates that line AB is parallel to line CD. In the Unicode character set, the "parallel" and "not parallel" signs have codepoints U+2225 (∥) and U+2226 (∦), respectively. In addition, U+22D5 (⋕) represents the relation "equal and parallel to".
The symbol for parallel lines is \(\parallel,\) so we can say that \(\overleftrightarrow{AB}\parallel\overleftrightarrow{CD}\) in that figure. According to the axioms of Euclidean geometry, a line is not parallel to itself, since it intersects itself infinitely often.

In geometry and mathematics, the ¶llel; symbol, known as the "Parallel To" symbol, is an essential notation. It indicates that two lines, planes, or other geometric entities run in the same direction without ever meeting, regardless of how far they are extended.

Oct 10, 2023 · Parallel lines are two or more lines that are always the same distance apart and never intersect, even if they are extended infinitely in both directions. They are always equidistant and run in the same direction, which means they have the same slope. These lines are a fundamental in geometry and have many real-world applications. Don’t believe us?
