Proving Triangles Similar: Multistep Transformations

Please watch this quick video to refresh you memory with how to use these transformational Geometry tools in GeoGebra.
IMPORTANT NOTES:
[list][*]When using the [b]DILATE FROM POINT[/b] [icon]/images/ggb/toolbar/mode_dilatefrompoint.png[/icon] tool, enter [i]"[/i]k" (without the " ") as your SCALE FACTOR. That way, you can adjust the value of k using the slider. [/*][*]When using the [b]ROTATE AROUND POINT[/b] [icon]/images/ggb/toolbar/mode_rotatebyangle.png[/icon] tool, use 90°, 180°, or 270° as your angle of rotation. [/*][/list]
