How to Write the Triangle Left Symbol (◁) in LaTeX

In LaTeX, you can write the triangle left symbol (◁) using the \triangleleft command.

The following examples show how to write the triangle left symbol in LaTeX.

How to Write the Triangle Left Symbol in Text

We can use the \triangleleft command to write the triangle left symbol in LaTeX document for text.

Suppose we want to write the triangle left symbol in the text.

We can use the following LaTeX code to do so:

\documentclass{article}
\begin{document}

This is an example of using the triangle left symbol \(\triangleleft\) in a sentence.

\end{document}

Output: 👇️

This is an example of using the triangle left symbol ◁ in a sentence.

In this example, we use the \triangleleft command to display the triangle left symbol in the text.

How to Write the Triangle Left Symbol in Mathematical Expressions

For mathematical expressions, we can use the \triangleleft command to ensure proper formatting.

Suppose we would like to write mathematical expressions that contain the triangle left symbol.

We can use the following LaTeX code to do so:

\documentclass{article}
\begin{document}

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

A displayed mathematical expression:
\[
A \triangleleft B = C
\]

\end{document}

Output: 👇️

In this example, we use the \triangleleft command to denote the triangle left symbol in both inline and displayed mathematical expressions.

Conclusion

We can use the \triangleleft command for both text and mathematical expressions. This ensures that the triangle left symbol is properly formatted and displayed in LaTeX document.
