Three Dimensional Angle ⟀

Usage snapshot:

• Used in content written with the Common script; suitable for UI labels and body text.
• Appears in the Unicode block Miscellaneous Mathematical Symbols-A.

History & usage: The character name is THREE DIMENSIONAL ANGLE. It depicts a symbol that signifies a geometric angle expressed with three dimensions. In the name, tokens show a numeric quantity (THREE) and a spatial concept (DIMENSIONAL ANGLE); such tokens signal the general role of numerals and shapes in technical notation. A qualifier like dimensions hints at a three‑axis context, while the form itself is a symbol rather than a letter. This matters for how it is used in reference works and displays, where operators and diagrams rely on compact, unambiguous marks. Use contexts include scholarly editions and paleography in the study of mathematical notation, where editors annotate diagrams and align marks across scripts. It also appears in educational primers and dictionaries that illustrate mathematical symbols, and in archival transcription where precise symbol shapes are cataloged. In typographic revivals and specimen books, it informs design choices for three‑dimensional symbol cues and symbol spacing. For quick UI work, it supports formulas, calculators, and comparison controls by providing a distinct, one‑line mark. Cross‑platform appearance should remain legible, with screen readers able to announce the symbol reliably.
