TrigonometryGeometric ConstructionGraphing
This example demonstrates the trajectory changes of two journeys with different speeds in a coordinate system. Core math concepts include interest calculation, isosceles triangles, trigonometric functions, correlation, and general quadrilaterals. Construction highlights involve commands like Polygon, RotateText, and Segment in GeoGebra. Suitable for high school mathematics teaching, focusing on the integration of function graphs and geometric transformations.

GeoGebra Commands & Parameters

  1. Polygon((0, 0), (7, 0), (7, 100), (0, 100)) → poly1, f, g, h, i
  2. RotateText("distance (kilometers)", 90°) → text3
  3. Segment(A, (x(A), 0)) → j
  4. Segment(C, (x(C), 0)) → k
  5. Segment(A, (x(A), y(C))) → l
  6. Segment(C, (0, y(C))) → m
  7. Segment(A, (0, y(A))) → n
  8. Segment(A, (x(C), y(A))) → r
