Sine Formula Demonstration

This example interactively demonstrates the application of the Sine Rule in triangles. It covers core concepts like the Sine Rule, triangle geometry, and vector operations. Construction involves commands like Segment, Angle, Polygon, Intersect, Line to build the triangle and auxiliary lines, defining sides a, b, c, and angles A, B, C, and calculating height h. Suitable for high school mathematics teaching to understand the proof and application of the Sine Rule.
