TransformationGeometric Construction
This example demonstrates a rectangle perimeter problem involving geometric transformations and algebraic operations. By adjusting the length and width of the rectangle, observe how the perimeter changes. It uses GeoGebra commands like Sequence and If for construction. Suitable for middle school and above students to learn about geometric transformations and algebraic relationships.

GeoGebra Commands & Parameters

  1. Sequence(Polygon[(0, ((i - 1) * h)), (w, ((i - 1) * h)), (w, (i * h)), (0, (i * h))], i, 1, m) → list1
  2. If(aspect ≤ a, (1.2 * (w + h) / aspect), ((1.2 * m) * h)) → winh
  3. Sequence(Polygon[(w, ((i - 1) * w)), (w + h, ((i - 1) * w)), (w + h, (i * w)), (w, (i * w))], i, 1, n) → list2
  4. If(aspect ≤ a, (1.2 * (w + h)), ((aspect * 1.2) * (m * h))) → winw
