TriangleTransformationGeometric Construction
This example demonstrates the dilation of a triangle. By using the dilation transformation, the concept of similarity transformation can be understood intuitively. The construction process uses commands such as points, polygons, and dilation. Suitable for students at the junior high school level and above to learn geometric transformations.

GeoGebra Commands & Parameters

  1. Polygon(A, C, B) → poly1, b, a, c
  2. Point(xAxis) → D
  3. Dilate(A, r, D) → A'
  4. Dilate(C, r, D) → C'
  5. Dilate(B, r, D) → B'
  6. Polygon(A', C', B') → poly1', b', a', c'

AI Drawing Prompt Reference

Draw a triangle ABC, then dilate it around a point D on the x-axis to create a new triangle A'B'C'. First, draw triangle ABC, then choose a point D on the x-axis as the center, and dilate points A, B, and C around D to create A', B', and C'. Finally, connect A', B', and C' to form triangle A'B'C'.
