This example demonstrates the triangle inequality theorem and side-angle relationships dynamically. It involves core math concepts like triangle inequalities, side-angle relations, and geometric constructions. Construction highlights include using Polygon, Point, Segment, Distance, Line, and Angle commands to create triangles and auxiliary segments, measuring side lengths and angles to verify a+b>c. Suitable for middle school students and math enthusiasts to visually understand geometric theorems.
