This example demonstrates the geometric properties of a rectangle. By constructing a rectangle, students can explore its angles, side lengths, and diagonals. GeoGebra commands such as Intersect, Circle, Point, and Line are used for geometric construction. Suitable for middle school and above students to learn geometry and trigonometry.

GeoGebra Commands & Parameters

  1. Intersect(xAxis, yAxis) → O
  2. Circle(O, r) → c
  3. Point(c) → A
  4. Line(A, O) → a
  5. Intersect(c, a) → B_1, C
  6. Rotate(C, α, O) → B
  7. Angle(C, O, B) → β
  8. Line(B, O) → b
  9. Intersect(c, b) → E, D
  10. Polygon(A, D, C, B) → P, a_1, f, c_1, d
  11. Segment(A, O) → e
  12. Segment(O, C) → g
  13. Segment(D, O) → h
  14. Segment(O, B) → i
  15. Angle(D, A, B) → γ
  16. Angle(C, D, A) → δ
  17. Angle(A, B, C) → ε
  18. Angle(B, C, D) → ζ
  19. Angle(D, O, C) → η
  20. Angle(A, B, D) → θ
  21. Angle(D, B, C) → ι

AI Drawing Prompt Reference

Draw a rectangle to explore its geometric properties such as angles, side lengths, and diagonals. Start by drawing a circle c centered at the origin O, then pick a point A on the circle and draw a line a through A and O, intersecting the circle at points B₁ and C. Rotate point C to get point B and measure the angle β at point C. Draw a line b through B, intersecting the circle at points E and D. Connect points A, D, C, and B to form rectangle P, and label its sides and angles such as ∠ADC and ∠BCD.
