PolygonTransformationGeometric Construction
This example demonstrates how to change the size of a polygon through dilation. Key math concepts include scale factor, perimeter, median line, etc. Construction highlights the use of GeoGebra commands like Point, Polygon, and Dilate to create points and polygons and perform dilation transformations. Suitable for middle school and above students learning and practicing geometric transformations.

GeoGebra Commands & Parameters

  1. Point(xAxis) → A
  2. Polygon(A, B, C) → poly1, c, a, b
  3. Dilate(A, 2.5, D) → A'
  4. Dilate(B, 2.5, D) → B'
  5. Dilate(C, 2.5, D) → C'
  6. Polygon(A', B', C') → poly1', c', a', b'
