TriangleMatrixTransformationGeometric Construction
This example demonstrates the rotation of a triangle around a point. It involves core math concepts like rotation matrices, isometries, and geometric constructions. GeoGebra commands used include Polygon, Intersect, and Point. Suitable for high school students to understand transformations and matrix applications.

GeoGebra Commands & Parameters

  1. Polygon(A, B, C) → poly1, c, a, b
  2. Intersect(xAxis, yAxis) → D
  3. Polygon(Rotate[A, α, D], Rotate[B, α, D], Rotate[C, α, D]) → Image, Image_2, Image_3, Image_4
  4. Point(Image) → E
  5. Intersect(Image_2, Image_3) → F
  6. Intersect(Image_3, Image_4) → G
