Circle Geometry Diagram: Perpendicular Diameters and Center Point #208104 (License: Personal Use)

This black-and-white geometric illustration depicts a perfect circle with two perpendicular diameters, AB (horizontal) and CD (vertical), intersecting precisely at the center point labeled O. The diagram is commonly used in mathematics education to explain concepts such as central angles, quadrants, radius equality, and the definition of a diameter. Its clean, minimal design emphasizes structural clarity for pedagogical purposes.

Used in educational web pages, math textbooks, or online tutorials covering Euclidean geometry, circle theorems, or coordinate geometry fundamentals; targets students and educators seeking visual reinforcement of core geometric principles.
