Observing Triangle Inequality

This example illustrates the geometric meaning of the triangle inequality. It involves the relationship between the sides of a triangle, where dragging points A, B, and C changes the shape of the triangle, allowing you to observe the inequality between the side lengths. The Polygon command is used to draw the triangle, and text objects are used to label the side lengths and inequalities. Suitable for middle school and above students to learn basic properties of triangles.
