120degree

120degree refers to the angle measurement of 120 degrees. It is an obtuse angle, meaning it is greater than 90 degrees but less than 180 degrees. In radians, 120 degrees equals 2π/3. On the unit circle, the trigonometric values are cos(120°) = -1/2, sin(120°) = √3/2, and tan(120°) = -√3.

In geometry, 120-degree angles appear prominently in regular hexagons, where each interior angle is 120°. The exterior angle of such a polygon is 60°, and three hexagons meeting at a vertex can fill a full 360 degrees, which relates to common tessellations and hexagonal tiling.

Beyond pure geometry, 120degree has applications in other domains. In color theory, a hue angle of 120° on the standard color wheel corresponds to green. In navigation, a bearing of 120° is measured clockwise from north and points roughly toward the southeast direction, depending on the reference frame.

The term is also encountered in mathematical notation and branding as a concise label for concepts or products associated with the 120-degree angle. In most contexts, 120degree is treated as a descriptive measurement rather than a separate mathematical constant, with its properties and implications derived from the geometry of a 120-degree angle.
