PolygonTransformationGeometric Construction
This example demonstrates how to construct the symmetry axis of a quadrilateral using GeoGebra. Key mathematical concepts include symmetry and geometric transformations. Commands used include Polygon, OrthogonalLine, Intersect, Segment, LineBisector, etc. Suitable for middle school and above students to learn about symmetry and geometric transformations.

GeoGebra Commands & Parameters

  1. Polygon(A, B, C) → poly1, c, a, b
  2. OrthogonalLine(A, a) → f
  3. Intersect(f, a) → D
  4. Segment(A, D) → g
  5. LineBisector(a) → h
  6. Intersect(h, a) → E
  7. Segment(A, E) → i
  8. AngularBisector(c, b) → j, k
  9. Intersect(k, a) → F
  10. Segment(A, F) → l
