VectorSolid GeometryGeometric Construction
This example demonstrates how to calculate the angle between two planes. It involves core mathematical concepts such as plane equations, vector dot product, and spatial geometry. The construction uses GeoGebra commands/objects like Segment, Line, Plane, Point, IntersectPath, PointIn, OrthogonalLine, and Vector. Suitable for high school geometry teaching and construction practice.
