PolygonTransformationGeometric Construction
This example demonstrates the concepts of perimeter, area, and similarity transformations. By dragging points A, B, and C, you can observe how the perimeter and area of the triangle change. The Dilate command is used for similarity transformations, allowing you to observe the properties of the transformed triangle. Suitable for students in middle school and above to learn about geometric transformations and similar triangles.

GeoGebra Commands & Parameters

  1. Polygon(A, B, C) → t1, c, a, b
  2. Dilate(A, 2, D) → A'
  3. Dilate(B, 2, D) → B'
  4. Dilate(C, 2, D) → C'
  5. Polygon(A', B', C') → t1', c', a', b'
  6. PointIn(t1') → Pointt1'_1
  7. PointIn(t1) → Pointt1_1
  8. Perimeter(t1') → perimetert1'
  9. PointIn(t1') → Pointt1'
  10. Perimeter(t1) → perimetert1
  11. PointIn(t1) → Pointt1
