How to insert angle symbol in Word

Often, in mathematical expressions, angles are marked by lowercase Greek letters: α, β, γ, θ, σ, etc. (see how to insert Greek letters quickly). Also, angles are denoted by three-point symbols, for example, ∠ ABC (where B is a vertex, and A and C are points on opposite sides of the corner).

Note: This tip is about inserting the angle into the text without using the Equation tools; see more about Word equations.

   I.  Using AutoCorrect for Math:

When you work with many documents and often need to paste just one special symbol, you don't need to insert an equation each time. Microsoft Word offers a helpful feature named AutoCorrect. The AutoCorrect options in Microsoft Word propose two different ways to quickly add any special character, such as angle, or even large pieces of text:

• Using the Replace text as you type function of the AutoCorrect options.
• Using the Math AutoCorrect options:

Using this method, you can benefit from the Math AutoCorrect options without inserting an equation. To turn on or turn off the AutoCorrect of the Math symbols, do the following:

   1.   On the File tab, click Options:

   2.   In the Word Options dialog box, on the Proofing tab, click the AutoCorrect Options... button:

   3.   In the AutoCorrect dialog box, on the Math AutoCorrect tab, select the Use Math AutoCorrect rules outside of the math regions option:

After clicking OK, you can use any of the listed Names of symbols, and Microsoft Word will replace them with the appropriate symbols:

Note: If you do not need the last replacement, click Ctrl+Z to cancel it.

   II.  Using a shortcut key:

In Microsoft Word, you can use Unicode to insert any of the used symbols:

	Shortcut key	Symbol
Angle	Type 2220 and press Alt+X	∠
Measured angle	Type 2221 and press Alt+X	∡

Note: You can see the combination in the Character code field in the Symbol dialog box (see below).

   III.  Using a Symbol dialog box:

To open the Symbol dialog box, on the Insert tab, in the Symbols group, select the Symbol button, and then click More Symbols...:

On the Symbol dialog box:

• In the Font list, select the Symbol font, and select the symbol:
  
• Click the Insert button to insert the symbol,
• Click the OK button to close the Symbol dialog box.
