How to Use and Format the Angle Symbol

Format ∠ according to its role as angle notation. ∠ is U+2220 ANGLE. It identifies an angle in geometry and is normally followed by point labels, a variable, or a measure statement. For the angle symbol, do not choose a character only because it looks similar to another glyph; verify U+2220 and keep the complete sequence together.

This page covers ∠; degree sign ° expresses an angular measure, and right-angle signs use different notation. For web content containing the angle symbol, literal UTF-8 text is preferred when the font supports it; complete decimal or hexadecimal references are also valid. When the angle symbol conveys an action, category, identity, hazard, measurement, or other essential information, pair it with readable text and an accessible name rather than relying on shape alone.

Place the vertex letter in the middle of a three-letter angle name.
Use ° after the numerical angle measure, not instead of ∠.
Use structured math markup in complex geometry expressions.
Use the exact encoded form U+2220 for angle symbol content.
Use UTF-8 text or complete numeric character references when publishing ∠ on the web.
Test ∠ in the target font, application, and screen-reader workflow.
Keep a visible text label near ∠ when readers may not recognize the glyph.

Angle Symbol Examples

∠ABC
m∠A = 45°
∠1 ≅ ∠2
∠ABC + ∠CBD
Right angle statement: m∠A = 90°
Unicode sequence for Angle Symbol: U+2220
HTML decimal: ∠
HTML hexadecimal: ∠
CSS escapes: 2220
Accessible text label: Angle Symbol

Common Angle Symbol Mistakes

Using ∠ as a degree sign.
Listing angle points in the wrong order when the vertex must be in the middle.
Confusing ∠ with less-than <.
Using a right-angle box when the angle is not known to be 90°.
Replacing the angle symbol with a lookalike without checking the code point or sequence.
Assuming the angle symbol has exactly the same glyph in every font and operating system.
Converting the angle symbol to an image when selectable and searchable text is required.
Using ∠ as the only accessible name of an interactive control.

More About the Angle Symbol

Angle Symbol uses ∠, U+2220 ANGLE. In geometry it names an angle, often with point labels such as ∠ABC. The vertex is normally the middle letter in that notation.

The measure of an angle is a different expression. Writing m∠A = 45° combines the angle symbol with a degree value. The degree sign supplies the unit of angular measure; it does not replace ∠.

Right-angle marks, measured-angle symbols, triangles, and less-than signs have separate code points and roles. A diagram or proof should use the notation required by its textbook, standard, or math-markup system.

Accessible math should be read as “angle ABC” or “measure of angle A,” not as a sequence of unexplained characters. Long or nested expressions are better represented with structured math markup than with plain text alone.

Unicode and NIST mathematical references support U+2220 and the notation boundary. The page is not expanded into a full geometry lesson or proof guide.

Practical strings already approved for Angle Symbol include ∠ABC, m∠A = 45°, ∠1 ≅ ∠2, ∠ABC + ∠CBD, and Right angle statement: m∠A = 90°. For Angle Symbol, they are drawn from equations, proofs, technical documents, and math education and should remain available as regression tests after any content or template update.

For encoded output on Angle Symbol, confirm that ∠ still resolves to U+2220. The Angle Symbol rules state: Place the vertex letter in the middle of a three-letter angle name. Use ° after the numerical angle measure, not instead of ∠. Use structured math markup in complex geometry expressions. Verification sources for Angle Symbol include Unicode, W3C/WCAG, WHATWG HTML, and NIST, with angle and Angle retained as lookup terminology.
