DSE Circle: Angle at Centre and Circumference Theorem
2016-12-19 06:42
This GeoGebra applet demonstrates the relationship between the angle at the centre and the angle at the circumference. It dynamically illustrates the theorem that the central angle is double the inscribed angle subtended by the same arc. Users can drag points to observe real-time angle changes, making it an ideal interactive tool for secondary school geometry education.
