This example explores the perimeter and area of rectangles using the coordinate axis. It demonstrates the basic geometric properties of rectangles, involving the concepts of area and perimeter. Using GeoGebra commands such as Intersect, OrthogonalLine, and Polygon, it shows how to construct geometric figures. Suitable for middle school and above students to learn geometry and algebra.

GeoGebra Commands & Parameters

  1. Intersect(xAxis, yAxis) → A
  2. OrthogonalLine(C, yAxis) → a
  3. OrthogonalLine(C, a) → b
  4. Intersect(a, yAxis) → B
  5. Intersect(b, xAxis) → D
  6. Polygon(A, B, C, D) → poly1, a_1, b_1, c, d
  7. Textfield(text1) → InputBox1
  8. Textfield() → InputBox2
  9. PointIn(poly1) → Pointpoly1_1
  10. Perimeter(poly1) → perimeterpoly1
  11. PointIn(poly1) → Pointpoly1_2
  12. PointIn(poly1) → Pointpoly1_3
  13. Perimeter(poly1) → e
  14. PointIn(poly1) → Pointpoly1_4
  15. Perimeter(poly1) → f
  16. PointIn(poly1) → Pointpoly1
