 # ∠ Angle

## Technical information

 Name Angle Unicode number U+2220 HTML-code ∠ CSS-code \2220 Entity ∠ Block Mathematical Operators Unicode version: 1.1 (1993)

## Symbol meaning

The sign denoting in a mathematical notation a geometric figure is an «angle» (and it is itself). Example of use: ∠ABC = 45 °.

The angle is formed by two rays emanating from one point (the top of the corner). It is often indicated by three points, ∠ABC. Here B is a vertex, and A and C are points lying on different rays (sides of the angle). The corners are given the designation in Greek letters, for example, ∠α.

The angle value (angular measure) can be calculated in different ways: in degrees, radians, turns or grads. If both sides of the angle lie on the same line, then this angle is called unfolded and its value is 180 °.

Angle was approved as part of Unicode 1.1 in 1993.
