This example demonstrates how to prove the area formula of a parallelogram by dividing it into triangles and rearranging them into a rectangle. Key math concepts include parallelogram properties, similar triangles, base, height, and area calculation. Constructed using GeoGebra commands like Point and Polygon for points A, B, C, D, base, height, and area. Suitable for middle school students and above to understand the derivation of the parallelogram area formula, or for classroom demonstrations.

GeoGebra Commands & Parameters

  1. Point(a) → C
  2. Polygon(A, B, D, C) → Area, base, height, d, c
  3. Polygon(Y, B', D') → poly1, d', E, b'
