The term "270°" refers to an angle measurement in degrees, commonly used in geometry and trigonometry. It represents three-quarters of a full rotation, which is 360°. In a standard coordinate system, an angle of 270° points directly downward along the negative y-axis. In practical applications, 270° can be seen in various fields, such as navigation and engineering. For instance, when using a compass, a bearing of 270° indicates a direction that is directly west. This angle is also relevant in the study of circles and trigonometric functions, where it helps define the position of points on a unit circle.
