Meaning & Usage in Geometry
The angle symbol ∠ marks an angle in a geometric figure or proof. Written before three points, such as ∠ABC, it names the angle at vertex B formed by rays BA and BC; the middle letter is always the vertex. It can also stand alone before a single letter, like ∠A, when only one vertex needs an angle in the figure.
In printed math and on the web, the character is often unavailable in a font or hard to type, so this page gives ready-to-paste versions for documents, HTML, and LaTeX.

How it works
- Click the large angle symbol to copy it to your clipboard.
- Or click any format in the list (Unicode, HTML entity, LaTeX) to copy that exact string.
- Use the related symbols table to copy the right angle, measured angle, or spherical angle sign instead.
- Paste the symbol anywhere: documents, spreadsheets, code, or chat.
Use cases
- Name an angle in a geometry proof or diagram, such as ∠ABC or ∠XYZ.
- Insert the angle symbol into a math worksheet, slide deck, or textbook without a font that supports it natively.
- Add the correct HTML entity to a web page instead of pasting a raw Unicode character.
- Write angle notation in LaTeX documents with the \angle command.
- Distinguish the plain angle symbol from the right angle or measured angle signs used in the same proofs.
