Perpendicular ⟂

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 depicts PERPENDICULAR. Functional tokens in the name include a clear semantic indicator rather than a phonetic sign; a perpendicular sign signals a right angle relationship in formulas. In general terms, such tokens mark operators or relations beyond letters, and shape or qualifier cues (like tall or broad) guide typographic emphasis or spacing in formulas. This symbol is used in geometry and math notation to denote orthogonality or a right angle between lines. 2–3 practical usage contexts: in scholarly editions of geometric treatises and in educational primers, the symbol appears to illustrate angle relationships and to label perpendicular lines. In archival transcription of mathematical texts, it helps preserve original notation across print and hand‑written sources. In quick UI contexts, calculators or symbolic formula editors use it as an operator in expressions to compute perpendicular relationships or constrain layouts. Since it belongs to the Miscellaneous Mathematical Symbols‑A block, its role matters for consistent typography and indexing of mathematical notation across educational materials. Cross‑platform rendering should respect accessibility by using descriptive alt text and scalable glyphs for screen readers.
