Angle Between 2 Vectors and Orthogonal Vectors Exercise

This example demonstrates how to draw two vectors in GeoGebra and calculate their angle, while checking for orthogonality. Core math concepts include vectors, angle between vectors, and orthogonality condition (dot product equals zero). Construction highlights: use Vector command for V and U, Angle command for θ, and auxiliary objects like u, v, O. Suitable for high school mathematics teaching to understand vector operations and spatial geometric relationships.
