6 Ways to Type the Congruent Symbol (≅) on Your Computer

Congruence in mathematics refers to the property of two objects being equal in shape and size. It is commonly employed to describe angles, shapes, and line segments. Symbolically, the congruent symbol is represented by an equals sign with a tilde over it (≅). Understanding the concept of congruence allows for the correct usage of this symbol.

However, when it comes to practical implementation, one may encounter challenges in producing the symbol within word processing programs or online platforms. Fortunately, there are multiple methods available for generating the congruent sign in various environments, including word processing programs, LaTex, and KaTex. These methods are straightforward to learn and apply.

Utilizing Copy and Paste

The most straightforward approach to employ the congruent symbol is by copying it from a reliable source that already incorporates the symbol and pasting it into the desired location. Follow these steps: highlight the symbol “≅,” press and hold the CTRL key, and simultaneously press the C key to copy it.

Then navigate to the intended location and press and hold the CTRL key, followed by the V key, to paste it. This method requires minimal effort and functions effectively across nearly all programs and environments. However, alternative methods are recommended for situations where a pre-existing congruent symbol example is unavailable, as they offer greater efficiency.

Microsoft Word or Google Docs

Microsoft Word and Google Docs are popular word processing programs widely used for creating documents. Both platforms offer convenient methods for typing the congruent symbol. In Microsoft Word, you can utilize the Symbols feature, which is readily available across different Word versions.

To access the Symbols feature in Word, select the Insert tab and locate the drop-down arrow beneath the Symbol option. Clicking on “More Symbols” will open the Symbol dialogue box.

In the Symbol dialogue box, choose “Mathematical Operators” from the Subset drop-down menu. Then, scan the grid of symbols until you find the congruent symbol. By left-clicking your mouse, highlight the symbol, and click “Insert” to place it at the cursor position within your document. If necessary, you can copy or cut the symbol and move it to a different location within your document.

Similarly, Google Docs provides a comparable feature for inserting symbols. However, the specific steps may vary slightly between the two platforms.

Streamlined Process in Office 365 Word:

In Office 365 Word, the process becomes even more streamlined. Navigate to the Insert tab on the ribbon and select Equation. Within the equation editor, locate the symbol grid on the ribbon and choose the congruent symbol. Click on it to automatically paste it into your document.

Simplified Process in Google Docs:

For Google Docs, the process is also simplified. Click on the Insert option at the top of the screen and select Special characters from the drop-down menu. In the window that appears, type “approximately equal to” in the search field.

The search results will display the congruent symbol—click on it to instantly insert it into your document. It’s important to note that both in Google Docs and Microsoft Word, the symbol is referred to as “approximately equal to.”

Congruent Sign Alt Code

An alternative method to produce symbols is by utilizing Alt codes, which can be used in most word processing programs and email platforms. This method requires a keyboard with a number pad section and ensures that Num Lock is activated. You can activate Num Lock by pressing the Num Lock key until the corresponding light turns on.

To generate the congruent symbol using Alt codes, hold down the Alt key while entering the code 8773.

Although memorizing the specific code might not be the most convenient solution, using the alt code method is often easier than searching for the symbol through other methods described earlier. Additionally, this method is compatible across multiple platforms, making it convenient for typing the symbol in various programs.

In LaTex or KaTex

LaTex is widely recognized for its ability to display mathematical equations and symbols. When using LaTex or KaTex, typing the congruent symbol is straightforward. Simply input “\cong” in the LaTex or KaTex field, and the congruent sign will be rendered accordingly.

Similarly, if you wish to create the symbol for “not congruent,” you can utilize “\ncong” in LaTex or KaTex. These commands ensure the correct display of the respective symbols in your document or equation.


In conclusion, understanding how to type the congruent symbol is crucial for effective mathematical communication. Whether you choose to copy and paste, use symbol insertion features in word processors, employ Alt codes, or utilize LaTex/KaTex commands, these methods enable you to accurately represent congruence in various contexts. Mastering these techniques empowers you to express mathematical ideas clearly and confidently.
