# How to Write the Congruent Symbol (≅) in LaTeX

In LaTeX, you can write the congruent symbol (≅) using the `\cong`

command.

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

## How to Write the Congruent Symbol in Text

We can use the `\cong`

command to write the congruent symbol in LaTeX document for text.

Suppose we want to write the congruent 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 congruent symbol \( a \cong b \) in a sentence.
\end{document}
```

Output: 👇️

```
This is an example of using the congruent symbol a ≅ b in a sentence.
```

In this example, we use the `\cong`

command to display the congruent symbol in the text.

## How to Write the Congruent Symbol in Mathematical Expressions

For mathematical expressions, We can use the `\cong`

command to ensure proper formatting.

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

We can use the following LaTeX code to do so:

```
\documentclass{article}
\begin{document}
An inline mathematical expression: \( a \cong b \).
A displayed mathematical expression:
\[
a \cong b
\]
\end{document}
```

Output: 👇️

In this example, we use the `\cong`

command to denote the congruent symbol in both inline and displayed mathematical expressions.

## Conclusion

We can use the `\cong`

command for both text and mathematical expressions. This ensures that the congruent symbol is properly formatted and displayed in LaTeX document.
