Angle

∠ is the angle sign: it identifies a geometric angle, while a degree value gives its size. Geometry used letter labels long before this mark; that practice is documented by about 440 BC. The recognizable ∠ appears beside < in Pierre Hérigone’s Cursus mathematicus in 1634 as angle notation; they are not interchangeable. Modern ∡ can mark a measured angle, while astrology also uses ∠ for the semisquare aspect.

What ∠ means

∠ is the angle. Unicode classifies it as a mathematical symbol and files it in the Mathematical Operators block; this site shelves it under Maths.

Its appearance depends on the font and text styling.

How it is encoded

∠ is a single code point, U+2220. In HTML that is ∠, and in CSS \2220.

Why does ∠ show as a box on some devices?

Because that device's fonts have no glyph for it. The character is still correct and still copies correctly — the box is a missing glyph, not a broken character.
