CircleAngleGeometric Construction
This example demonstrates the properties and theorem of inscribed angles in a circle, including relationships between central angles, inscribed angles, and similar triangles. It is constructed using GeoGebra commands such as Circle, Point, Segment, CircleArc, Angle, Line, Tangent, and Intersect. Suitable for high school mathematics education to understand the theorem and its applications.
