This example demonstrates how to calculate the angle between two vectors using their direction vectors. Key math concepts include vectors, direction vectors, vector angle calculation formulas, and vector applications in analytical geometry. The construction highlights the use of GeoGebra's IntersectPath command to find intersections of paths, determining vector directions and calculating angles. Suitable for high school and above learners to understand the integration of vector operations and geometric constructions.

GeoGebra Commands & Parameters

  1. IntersectPath((x - 2) / 3 + (0 * z) = (y + 4) / 2, (x - 2) / 3 = z - 1) → f
  2. IntersectPath((x + 3) / 4 + (0 * z) = y / 3, (x + 3) / 4 = (z - 3) / -5) → g
