PolygonVectorTransformation
This example demonstrates the dilation of quadrilaterals JKLM and WXYZ. Key mathematical concepts include similarity transformation and polygons. Using GeoGebra commands such as Point, Polygon, Intersect, and Dilate, similar quadrilaterals can be constructed. Suitable for students at the junior high school level and above to learn about similarity transformations.

GeoGebra Commands & Parameters

  1. Point(yAxis) → J
  2. Polygon(J, K, L, M) → q1, a, b, c, d
  3. Intersect(xAxis, yAxis) → A
  4. Dilate(J, 2 / 3, A) → W
  5. Dilate(K, 2 / 3, A) → X
  6. Dilate(L, 2 / 3, A) → Y
  7. Dilate(M, 2 / 3, A) → Z
  8. Polygon(W, X, Y, Z) → q1', j', k', l', m'
