Geometric Interpretation and Construction of Vector Subtraction

This example demonstrates the geometric meaning of vector subtraction and its construction method. It uses GeoGebra's Vector command to construct vectors and Translate command for vector translation, showing how to obtain the vector difference through translation. The core mathematical concepts include vector coordinate representation, the triangle rule and parallelogram rule for vector subtraction. Key construction points: use the Vector command to define directed line segments as vectors, apply the Translate command to move vectors to specified positions, and visually demonstrate vector subtraction through triangle or parallelogram construction. Suitable for high school vector teaching, teacher training, and as a visualization tool for vector operations.
