Right angle arc (⊾) is the Unicode character at U+22BE in the Mathematical Operators block. Official name: RIGHT ANGLE WITH ARC. It marks a 90° angle with an arc — used in geometry and math notation.
Remember
Character ⊾
Unicode U+22BE
Named entity ⊾
Hex entity ⊾
Decimal ⊾
CSS escape \22BE
Not the same ∟ · ∠ · ∡
Prefer ⊾ in HTML markup. You can also type ⊾ in UTF-8, or use numeric forms when needed.
Right Angle Arc using Named Entity: ⊾
Right Angle Arc using Hex Code: ⊾
Right Angle Arc using HTML Code: ⊾
Right Angle Arc using CSS Entity: ⊾
Typed directly: ⊾
Geometry: ∠ABC = 90° ⊾
How It Works
1. Named:⊾ is the HTML5 name for U+22BE → ⊾. Best default in markup.
2. Hex:U+22BE → ⊾ in HTML. Same glyph as the named form.
3. Decimal: same code point as 8894 → ⊾. Same result as hex and named.
4. CSS: use \22BE in content (not an HTML entity). #point::after appends that ⊾ after the paragraph text.
5. Typed / geometry: paste ⊾ in UTF-8, or write ∠ABC = 90° ⊾ for a short geometry example.
Pitfalls & Tips
Common mistakes when working with Right Angle Arc.
∟
Not the same as ∟
∟ is plain right angle (∟). ⊾ adds the arc (⊾). Pick the one that matches your diagram.
∠
Not a general angle
∠ (∠) is the open angle mark. Use it for ∠ABC-style naming — not for a dedicated right-angle-with-arc glyph.
Name
Remember ⊾
The named entity ends with vb (vertical bar / arc form in MathML naming). Do not invent &angrtarc;.
CSS vs HTML
Do not mix escapes
\22BE belongs in CSS strings. ⊾ / ⊾ / ⊾ belong in HTML.
Fonts
Math font coverage
Some UI fonts omit Mathematical Operators. Prefer a font with solid math coverage for display.
Semicolon
End named entities
Always finish with ; — write ⊾, not &angrtvb.
Compatibility
Browser Support
Right angle arc (U+22BE) and its entity forms (⊾, ⊾, ⊾, CSS \\22BE) are supported in all mainstream browsers. Visible glyphs depend on math font coverage.
✓ Universal support
Right Angle Arc (⊾)
Encode with named, hex, decimal, CSS escape, or type the character — same code point everywhere encoding is supported.

Bottom line: Prefer ⊾ in HTML. Use ⊾ / ⊾ when numeric form is required, and \\22BE only inside CSS content.
Remember
Key Takeaways
Unicode: right angle arc is U+22BE (decimal 8894) — glyph ⊾.
HTML: prefer ⊾ — also ⊾ / ⊾ / type ⊾.
CSS: use \22BE inside content for generated text.
Meaning:⊾ = right angle with arc — not ∟, not ∠.
Prefer ⊾ (named). You can also use ⊾ (hex), ⊾ (decimal), type ⊾ in UTF-8, or the CSS escape \22BE in content.
U+22BE (RIGHT ANGLE WITH ARC). Hex 22BE, decimal 8894. It belongs to the Mathematical Operators block (U+2200–U+22FF).
Yes. Use ⊾. Numeric forms ⊾ and ⊾ also work. Prefer the named form for readable markup.
Use it in geometry and math when you need a right angle marked with an arc (90° with arc). Prefer ∟ for a plain right angle and ∠ for a general angle.
HTML entities (⊾, ⊾, or ⊾) go in markup. The CSS escape \22BE goes in stylesheet strings (usually content on ::before/::after).
No. ⊾ is U+22BE (right angle with arc, ⊾). ∟ is U+221F (right angle, ∟). ∠ is U+2220 (angle, ∠).

Did you know?
Right angle arc is Unicode U+22BE (decimal 8894) — glyph ⊾ in Mathematical Operators. Official name: RIGHT ANGLE WITH ARC. HTML5 names it ⊾. Prefer ⊾ in markup. Plain right angle is ∟ (U+221F); general angle is ∠ (U+2220).
