This example demonstrates the triangle inequalities, which are important properties of the lengths of the sides of a triangle. Using GeoGebra commands such as Point, Segment, and Polygon, it dynamically shows the relationship between the lengths of the sides of a triangle. Suitable for students in middle school and above to learn about geometry and inequalities.
