This example demonstrates how to perform reflections or rotations using GeoGebra. Key mathematical concepts include reflection and rotation. Using commands like Point, Polygon, and Rotate, you can construct shapes with reflection or rotation properties. Suitable for middle school and above students or teachers for geometry construction lessons.

GeoGebra Commands & Parameters

  1. Point(yAxis) → C
  2. Polygon(A, B, C) → poly1, c, a, b
  3. Point(xAxis) → D
  4. Rotate(A, 180°, D) → A'
  5. Rotate(B, 180°, D) → B'
  6. Rotate(C, 180°, D) → C'
  7. Polygon(A', B', C') → poly1', c', a', b'
