Frog Stretcher

Stretcher Tool

Sorry, the GeoGebra Applet could not be started. Please make sure that Java 1.4.2 (or later) is installed and activated. (click here to install Java now)

Stretch the frog by changing the multiplier (point B on the horizontal axis.)
Change the height of the original (green) frog by moving the point D up or down.
The red frog is the result of stretching.

You can also use this tool to multiply two numbers, such as 0.75 times 1.2. Double click on B under "Free objects", and change it to (0.75,0). Double click on D and change it to (1,1.2).

What happens when you stretch by a small number (between 0 and 1)?

What happens when one or both of the factors are negative?
