Triangle Inequality Demonstration by Alexander Lau

This example visually demonstrates the triangle inequality theorem, showing the relationship between the lengths of the sides of a triangle. Key math concepts include triangle inequality, polygon construction, and distance calculation. It uses GeoGebra commands like Polygon and Distance, with objects such as points A, B, C, polygon poly1, variables c, a, b, d, and text elements. Suitable for middle school and above mathematics education to intuitively understand geometric inequality theorems.
