This example demonstrates how to model percentage increase and decrease using geometric figures and function graphs. Key mathematical concepts include linear equations, percentage calculations, and geometric transformations. Construction involves GeoGebra commands such as Textfield, Intersect, Point, Polygon, etc. Suitable for middle or high school mathematics teaching to understand the relationship between percentage changes and geometric shapes, and the dynamic changes in function graphs.

GeoGebra Commands & Parameters

  1. Textfield(k) → InputBox1
  2. Textfield(e) → InputBox2
  3. Textfield(l) → InputBox3

  5. Point(xAxis) → F
  6. Polygon(F, L, J, G) → q4, j, m, n, p
  7. Segment(E, F) → f
  8. Segment(F, G) → g
  9. Segment(G, H) → h
  10. Segment(H, E) → i
  11. Mirror(C, F) → C'
  12. Mirror(N, F) → N'
  13. Polygon(F, N, O, G) → q3, f_3, n_1, o_1, g_3
  14. Polygon(F, G, P, N') → q5, f_4, g_4, p_1, n'

AI Drawing Prompt Reference

Draw a geometric figure to model percentage increase and decrease. The figure should include a central point, two line segments, and a triangle. The construction order is to first draw the central point, then connect it to two endpoints to form line segments, and then use these endpoints to create the triangle. The figure should clearly show the relationship between percentage changes and geometric shapes, suitable for math teaching.
