TriangleInequality
This example demonstrates the inequalities of a triangle. Key mathematical concepts include the relationship between the sides of a triangle. Using GeoGebra commands such as Point and Segment, a dynamic triangle can be constructed and the side length relationships observed. Suitable for middle school and above students to learn about triangle inequalities.
