Intersecting Secants: Composite Segment Lengths

This example demonstrates the segment length relationships formed by two intersecting secants inside a circle, providing dynamic verification of the intersecting secants theorem. Core mathematical concepts include circles, secant lines, line segments, intersection points, distance measurement, and arithmetic operations. The construction uses GeoGebra commands such as Circle, Point, Segment, Line, Intersect, Distance, Angle, and Rotate, creating objects including points A, B, C, D, E, F, G and segments FC, FE, FD, FG to dynamically display segment lengths through intersection and distance measurement. Suitable for high school geometry instruction on circle-line relationships, classroom demonstrations, and independent exploration, helping students grasp the geometric meaning of the product theorem for intersecting secant segment lengths.
