This image displays a clean, minimalist illustration of a circular sector-a region bounded by two radii and the included arc. The red outline emphasizes the geometric boundaries against a neutral beige background, making it ideal for educational diagrams. It’s commonly used to explain concepts like central angles, arc length, and sector area in mathematics.

Used in educational web pages, math tutorials, geometry guides, or interactive learning platforms where users seek visual clarification of sector properties; matches intent for “what is a sector” or “sector diagram” searches.
