This example demonstrates how to calculate the area of a parallelogram using vector cross product. Core math concepts include vectors, vector cross product, and geometric construction. Construction highlights: Point, Polygon, Text commands are used to create points u, v, w, A, B, C, D, polygon poly1, vectors a, b, c, d, and text text1. Suitable for high school mathematics teaching and geometric construction learning.

GeoGebra Commands & Parameters

  1. Point(w) → A
