Proving Triangles Similar: Multistep Transformations

Auteur :Tim Brzezinski

Please watch this quick video to refresh you memory with how to use these transformational Geometry tools in GeoGebra.

IMPORTANT NOTES:

  • When using the DILATE FROM POINT Toolbar Image tool, enter "k" (without the " ") as your SCALE FACTOR. That way, you can adjust the value of k using the slider.
  • When using the ROTATE AROUND POINT Toolbar Image tool, use 90°, 180°, or 270° as your angle of rotation.
