Planar Transformations

This applet helps students walk-through the basic planar transformations such as translation, reflection, dilation/constriction, and rotation.
Here a triangle is experiencing the transformations with respect to a line and a point.

Drag the steps slider to see each step of the different transformations.

Sorry, the GeoGebra Applet could not be started. Please make sure that Java 1.4.2 (or later) is installed and active in your browser (Click here to install Java now)

Click and drag any point on the original triangle, line segment, or point to see how all the transformations are affected.
