FunctionSequenceGeometric Construction
This example demonstrates the generation of triangular, oblong, and square numbers. Key mathematical concepts include sequences and geometric shapes. Using GeoGebra commands such as Sequence and Polygon, the generation process of these sequences is dynamically shown. Suitable for middle school and above students to learn about sequences and geometric shapes.

GeoGebra Commands & Parameters

  1. Sequence(Sequence[(i, j), i, j, n], j, 1, n) → triangularNumbers
  2. Sequence(Sequence[(i, j), i, 1, n], j, 1, n) → squareNumbers
  3. Sequence(Sequence[(i, j), i, 1, n], j, 1, n + 1) → oblongNumbers
  4. Polygon((1, 1), (n, 1), (n, n), (1, 1)) → trianglePoly, f, g, h, i
  5. Polygon((1, 2), (n, n + 1), (1, n + 1), (1, 2)) → oblongPoly, j, k, l, m
  6. Polygon((1, 2), (n - 1, n), (1, n), (1, 2)) → squarePoly, p, q, r, s
