PolygonCoordinate GeometryGeometric Construction
This example demonstrates the calculation of the area of a square. Key mathematical concepts include geometric area calculation and coordinate geometry. Using GeoGebra commands such as Polygon, Point, Sequence, etc., it dynamically shows the change in the area of a square. Suitable for middle school and above students to learn geometry and area calculation.

GeoGebra Commands & Parameters

  1. Polygon(A_1, B_1, C, D) → pol1, a, b, c, d
  2. Point(a) → E
  3. Point(d) → G
  4. Polygon(H_1, I, J, K) → pol3, h_1, i, j, k
  5. Midpoint(c) → L_1
  6. Midpoint(b) → M
  7. Join(Sequence[Sequence[(i, j), i, 0, L - 1], j, 0, L - 1]) → L1
  8. Sequence(Polygon[Element[L1, i], (x(Element[L1, i] + 1), y(Element[L1, i])), 4], i, 1, n) → L2
