The interactive sides to angles and hypotenuse calculator.
By: Pedro Izecksohn , izecksohn at yahoo dot com
After you click inside the applet, use your arrows to make the triangle grow.
The legs are measured in pixels. The angles are calculated (from radians) to degrees. Hypotenuse's size is calculated, so it differs from the number of pixels used to draw it. All calculations are made using double, but are shown rounded to float. NaN angles are not shown.

If you can not see the applet, but you are seeing an empty box, it is because you do not have Sun Microsystems' Java 6.0 (code named Mustang) plugin installed.
In Mozilla Firefox 1.5 for Linux, when the applet is focused, some times it does not receive KeyEvents.
