Coordinate GeometryTransformationGeometric Construction
This example demonstrates congruence transformations, specifically reflections. The core mathematical concept is reflection transformation. Using GeoGebra commands such as Point, Line, and Mirror, the reflection transformation is constructed. Suitable for students at the middle school level and above for learning geometric transformations.

GeoGebra Commands & Parameters

  1. Point(yAxis) → B
  2. Point(yAxis) → C
  3. Line(B, C) → f
  4. Point(xAxis) → E
  5. Line(D, E) → g
  6. Mirror(f, yAxis) → f'
  7. Mirror(f', f) → f''
