This example demonstrates the relationship between a single triangle and component vectors in a state of physical equilibrium. Core math concepts include vectors, triangles, angles, length calculations, and orthogonal lines. It is constructed using GeoGebra commands and objects like Segment, Point, Line, Intersect, Vector, Translate, Angle, OrthogonalLine, Length, SelectedElement. Suitable for high school physics and mathematics teaching to understand force equilibrium and vector decomposition.
