Trivial Example with Three Points

This example demonstrates the construction of a polygon from three points and related vectors and domains. Core math concepts include vectors, polygon construction, definite integral, and trigonometry. GeoGebra commands like Vector, Polygon, and DomZone are used to create objects such as α_1, α_2, F1, F2, showcasing spatial relationships between vectors and polygons. Suitable for high school and above learners to understand vector operations and polygonal geometry.
