Vector Angle Calculation in a Triangular Prism

This GeoGebra example illustrates using vector algebra to determine the angles between faces and edges within a triangular prism. Key mathematical concepts include the dot product, angle formula between vectors, 3D coordinate geometry, and spatial visualization of polyhedral faces. Construction employs GeoGebra commands such as Intersect, Point, and Prism, with defined points (A, B, C, D, E, F) and face/edge objects to build the 3D model and compute precise angle measurements. Ideal for high school and early university students studying solid geometry, vector analysis, and spatial reasoning, it provides a dynamic platform for exploring how vector methods simplify angle calculation in three-dimensional shapes.
