Coordinate GeometryTransformationGeometric Construction
This example demonstrates the transformation of shapes under dilation, involving core math concepts like dilation, similar figures, and coordinate geometry. It uses commands and objects such as Segment, Point, and Dilate in GeoGebra. Suitable for high school students learning geometric transformations and analytical geometry.

GeoGebra Commands & Parameters

  1. Segment(A, C) → f
  2. Segment(A, B) → g
  3. Point(xAxis) → O
  4. Dilate(A, k, O) → A'_2
  5. Dilate(pic1, k, O) → pic1'
  6. Dilate(A, k, O) → A'
  7. Dilate(B, k, O) → B'
  8. Segment(A', B') → g'
  9. Segment(O, A') → h
  10. Segment(O, A) → i
  11. Segment(O, B') → j
  12. Segment(O, B) → l

AI Drawing Prompt Reference

Draw a similarity transformation with the origin as the center. First, draw two line segments AB and AC. Then, take point O on the x-axis as the center and dilate point A and line segment AB to get point A' and line segment A'B'. Next, draw the line connecting A' and B', and the line segments from O to A', A, B', and B. Observe the changes between the original and the dilated figures.
