Coordinate GeometryTransformationGeometric Construction
This example demonstrates how to locate the center of a dilation transformation by manipulating geometric figures. Key math concepts include similarity, central symmetry, and coordinate geometry. GeoGebra commands and objects used are Polygon, Dilate, and Line. Suitable for high school mathematics education to understand the properties and applications of dilation transformations.

GeoGebra Commands & Parameters

  1. Polygon(A, B, C, D, E, F) → poly1, a, b, c, d, e, f
  2. Dilate(A, g, G) → A'
  3. Dilate(B, g, G) → B'
  4. Dilate(C, g, G) → C'
  5. Dilate(D, g, G) → D'
  6. Dilate(E, g, G) → E'
  7. Dilate(F, g, G) → F'
  8. Polygon(A', B', C', D', E', F') → poly1', a', b', c', d', e', f'
  9. Line(G, F) → h
  10. Line(E, E') → i
  11. Line(D', D) → j
  12. Line(C', C) → k
  13. Line(B', B) → l
  14. Line(A, A') → m

AI Drawing Prompt Reference

Draw a hexagon ABCDEF, then perform an enlargement transformation around a center point G to get a new hexagon A'B'C'D'E'F'. Next, draw the perpendicular bisectors of the corresponding sides of the new hexagon A'B'C'D'E'F' and the original hexagon ABCDEF. The intersection points of these perpendicular bisectors are the center point G of the enlargement transformation.
