TriangleTransformationGeometric Construction
This example demonstrates constructing congruent triangles through reflection. Key mathematical concepts include congruent triangles and reflection transformations. It uses commands like Polygon, Line, Point, Mirror, and Distance in GeoGebra. Suitable for middle school geometry lessons, helping students understand the properties of congruent triangles and the application of reflection transformations.

GeoGebra Commands & Parameters

  1. Polygon(A, B, C) → poly1, c, a, b
  2. Line(A, C) → f
  3. Point(c) → D
  4. Point(a) → E
  5. Mirror(E, f) → G
  6. Mirror(D, f) → F
  7. Distance(D, A) → distanceDA
  8. Distance(F, A) → distanceD'A
  9. Distance(E, C) → distanceEC
  10. Distance(G, C) → distanceE'C
