Angle ∠
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 °.
The symbol “Angle” is included in the “Angles” subblock of the “Mathematical Operators” block and was approved as part of Unicode version 1.1 in 1993.
