PolygonGeometric Construction
This example demonstrates how to calculate the area and perimeter of polygons using GeoGebra. It involves core mathematical concepts such as area, perimeter, equations, random variables, special points, and random experiments. The construction uses GeoGebra commands and objects like Point, Polygon, Dilate, PointIn, and Perimeter. Suitable for middle school students and above to explore the properties of geometric figures.

GeoGebra Commands & Parameters

  1. Point(yAxis) → D
  2. Polygon(B, C, D) → poly1, d, b, c
  3. Dilate(B, 0.5, A) → B'
  4. Dilate(C, 0.5, A) → C'
  5. Dilate(D, 0.5, A) → D'
  6. Polygon(B', C', D') → poly1', d', b', c'
  7. PointIn(poly1') → Pointpoly1'_1
  8. PointIn(poly1) → Pointpoly1_1
  9. Perimeter(poly1') → perimeterpoly1'
  10. PointIn(poly1') → Pointpoly1'
  11. Perimeter(poly1) → perimeterpoly1
  12. PointIn(poly1) → Pointpoly1
