This example demonstrates how to calculate and visualize the area and perimeter of polygons and circles using GeoGebra. Key math concepts include area, perimeter, polygon construction, and properties of circles. It utilizes commands like Sequence, Polygon, Circle, and Point. Suitable for middle school students learning basic geometric properties and calculations.

GeoGebra Commands & Parameters

  1. Sequence((x(A) + (unitsize * i), y(A)), i, 1, base) → list1
  2. Sequence((x(A) + (unitsize * i), y(A) + (hauteur * unitsize)), i, 1, base) → list2
  3. Sequence((x(A), y(A) + (unitsize * i)), i, 1, hauteur) → list3
  4. Sequence((x(A) + base, y(A) + (unitsize * i)), i, 1, hauteur) → list4
  5. Polygon(A, Element[list1, base], Element[list2, base], Element[list3, hauteur]) → poly1, a, b, c, d
  6. Circle(B, unitsize) → f
  7. Point(f) → C
  8. Circle(C, unitsize) → g
  9. Polygon(B, C, 4) → poly2, h, i, j, k, D, E
  10. Sequence(Segment[(x(A), y(A) + (unitsize * i)), (x(A) + (base * unitsize), y(A) + (unitsize * i))], i, 0, hauteur) → dottedhorizontals
  11. Sequence(Segment[(x(A) + (unitsize * i), y(A)), (x(A) + (unitsize * i), y(A) + (hauteur * unitsize))], i, 0, base) → dottedverticals
