Angle at the Centre Theorem Demo
Loading the math board and drawing, please wait…
This example demonstrates the Angle at the Centre Theorem, showing the relationship between the central angle and the arc it subtends. Key math concepts include circles, angles, and geometric construction. It uses GeoGebra commands like Circle, Point, Polygon, and Angle. Suitable for middle school and above students to learn and understand circle properties, ideal for geometry teaching demonstrations.
