Dilating a pentagon

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)

Dilation is a technique for creating similar figures.

Each point is stretched outwards from the center point D by multiplying distances by the scale factor. (Outwards if the scale factor is bigger than 1.)

Move the points A, B, C, D, E to change the shape of the pentagon.
Move the center point F to dilate from a different location.
Use the slider to change the scale factor.
