Spherical Angle Opening Left Symbol

⦠ denotes a left-opening spherical angle in mathematical notation.

U+29A0

The symbol ⦠ is called “Spherical Angle Opening Left” and is commonly used in math typography. It can help convey spherical angle geometry when you need a dedicated opening glyph. Below you’ll find practical ways to copy and use it.

Spherical Angle Opening Left Symbol Meaning

⦠ (Unicode U+29A0) is the “SPHERICAL ANGLE OPENING LEFT” symbol. In mathematical and technical contexts, it’s used as a specific bracket-like mark to represent an opening for a spherical angle, typically indicating orientation (here, opening to the left). Compared with more general angle brackets, this glyph is intended for specialized geometry notation where spherical angles are being expressed. You’ll most often see it in typeset formulas, handwritten-style math renderings, or document systems that support Unicode math symbols. When you use it, ensure your font and renderer display the character correctly to preserve the intended notation.

Common uses

  • Represent spherical angle notation in math documents
  • Use as an opening delimiter in technical equations
  • Label or annotate spherical geometry figures in reports
  • Create consistent symbol styling in math-heavy design work
  • Add specialized math symbols in Unicode-capable editors

Examples

⦠ Spherical Angle Opening Left

  • Use ⦠A⦡ to indicate a left-opening spherical angle region.
  • The mark ⦠ is placed before the angle arc in the diagram caption.
  • Let ⦠θ denote the spherical angle opening left in the derivation.
  • In the formula, replace a generic bracket with ⦠ for spherical geometry.
  • The notation uses ⦠ to match the leftward orientation of the angle.
