TrigonometryCoordinate GeometryGeometric Construction
This example demonstrates geometric constructions like rhombuses, scatter plots, and median lines using GeoGebra, analyzing their properties. Core concepts include addition, scatter plots, congruence, median lines, rhombuses, and cosine theorem. Construction highlights the use of Point, OrthogonalLine, Intersect, and Circle commands/objects. Suitable for middle school and above students learning geometric constructions, data analysis, and trigonometric applications.

GeoGebra Commands & Parameters

  1. Point(xAxis) → A
  2. Point(yAxis) → B
  3. OrthogonalLine(A, xAxis) → a
  4. OrthogonalLine(B, yAxis) → b
  5. Intersect(a, b) → C
  6. Circle(A, C) → c
  7. Intersect(c, xAxis, 1) → D
  8. Intersect(c, xAxis, 2) → E

AI Drawing Prompt Reference

Draw a coordinate system with x and y axes. Take points on each axis, then draw perpendicular lines from these points to the axes. The intersection of these lines is point C. Draw a circle centered at A and C, intersecting the x-axis at points D and E.
