PolygonTransformationGeometric Construction
This example demonstrates the geometric transformation process of rotating a polygon around a fixed point. Core math concepts include rotation, angles, polygon construction, and geometric transformations. Construction highlights involve using GeoGebra commands like Polygon, Line, and Rotate. Suitable for high school mathematics teaching or geometric transformation learning, helping to understand the properties and applications of rotational transformations.

GeoGebra Commands & Parameters

  1. Polygon(A, B, C) → poly1, c, a, b
  2. Polygon(A', B', C') → poly3, f, d, e
  3. Line(D, E) → g
  4. Rotate(B, α, O) → target2
  5. Rotate(A, α, O) → target1
  6. Rotate(C, α, O) → target3
  7. Polygon(target1, target2, target3) → poly1', c'_1, a'_1, b'_1
