TriangleTransformationGeometric Construction
This example demonstrates the dynamic rotation of a triangle around a point. It involves core math concepts like rotation, similar triangles, and geometric transformations. GeoGebra commands used include Polygon, Intersect, and Rotate. Suitable for middle school and above students learning geometric transformations and spatial reasoning.

GeoGebra Commands & Parameters

  1. Polygon(A, B, C) → poly1, c, a, b
  2. Intersect(xAxis, yAxis) → D
  3. Rotate(A, α, D) → A'
  4. Rotate(B, α, D) → B'
  5. Rotate(C, α, D) → C'
  6. Polygon(A', B', C') → poly1', c', a', b'
