PolygonAngleTransformation
In collections Learn GeoGebra Classic
This example demonstrates how to rotate polygons. Key mathematical concepts include rotation transformation and angles. It uses commands like Polygon, Intersect, Rotate, Segment, and Angle in GeoGebra. Suitable for middle school and above students learning geometric transformations.

GeoGebra Commands & Parameters

  1. Polygon(A, B, C) → poly1, c, a, b
  2. Intersect(xAxis, yAxis) → O
  3. Rotate(A, α, O) → A'
  4. Rotate(B, α, O) → B'
  5. Rotate(C, α, O) → C'
  6. Polygon(A', B', C') → poly1', c', a', b'
  7. Segment(A, O) → d
  8. Segment(O, A') → e
  9. Angle(A, O, A') → β
