This example demonstrates the ratio and geometric transformation in a double LEGO gear train. Key mathematical concepts include geometric ratios, geometric mean, and geometric transformations. Construction involves GeoGebra commands such as SelectedElement, Segment, gear_1, a_1, α_1, A_1, etc. It is suitable for middle school or high school students to learn geometric ratio and parametric equation drawing techniques.

GeoGebra Commands & Parameters

  1. SelectedElement(gear_1) → a_1
  2. SelectedElement(gear_2) → a_2
  3. SelectedElement(gear_3) → a_3
  4. SelectedElement(gear_4) → a_4
  5. Segment(A_3, A_2) → a

AI Drawing Prompt Reference

Draw a double gear train consisting of four gears arranged in two meshing pairs, showing two gear ratios. Connect the centers of two specific gears with a line segment to illustrate their geometric relationship. The radii of the gears should reflect proportional ratios, emphasizing geometric mean and transformations. The layout should be clear, with gears sized proportionally and the segment as a reference line.
