How to Write the Not Parallel Symbol (∦) in LaTeX

In LaTeX, you can write the not parallel symbol (∦) using the \nparallel command. This command is part of the amssymb package, so you need to include this package in LaTeX document.

The following examples show how to write the not parallel symbol in LaTeX.

How to Write the Not Parallel Symbol in Text

We can use the \nparallel command to write the not parallel symbol in LaTeX document for text.

Suppose we want to write the not parallel symbol in the text.

We can use the following LaTeX code to do so:

\documentclass{article}
\usepackage{amssymb}
\begin{document}

This is an example of using the not parallel symbol \( A \nparallel B \) in a sentence.

\end{document}

Output: 👇️

This is an example of using the not parallel symbol A ∦ B in a sentence.

In this example, we use the \nparallel command to display the not parallel symbol in the text.

How to Write the Not Parallel Symbol in Mathematical Expressions

For mathematical expressions, We can use the \nparallel command to ensure proper formatting.

Suppose we would like to write mathematical expressions that contain the not parallel symbol.

We can use the following LaTeX code to do so:

\documentclass{article}
\usepackage{amssymb}
\begin{document}

An inline mathematical expression: \( A \nparallel B \).

A displayed mathematical expression:
\[
A \nparallel B
\]

\end{document}

Output: 👇️

In this example, we use the \nparallel command to denote the not parallel symbol in both inline and displayed mathematical expressions.

Conclusion

We can use the \nparallel command from the amssymb package for both text and mathematical expressions. This ensures that the not parallel symbol is properly formatted and displayed in LaTeX document.
