Negative Angle Definition and Visualization in Trigonometry #295646 (License: Personal Use)

This black-and-white line diagram depicts an angle in standard position where the initial side lies along the positive x-axis (OX), and the terminal side rotates clockwise to point P, forming a negative angle denoted as (b). The vertex is labeled O, and the curved arrow indicates the direction of rotation. Such diagrams are foundational for understanding angle measurement conventions in coordinate geometry and trigonometric functions.

Used in educational math resources, trigonometry textbooks, or online learning modules to explain angle directionality; matches user intent for visual clarification of negative angle definitions and standard position conventions.
