This example demonstrates the relationship between segment lengths of intersecting secants according to the first formula. It involves core math concepts like the intersecting secants theorem and inequalities. Constructed using GeoGebra commands such as Circle, Point, Segment, Intersect, and Distance to create the geometry and measure distances. Suitable for high school students and geometry enthusiasts learning or verifying geometric theorems.
