Just type in the coordinates of three points each for plane 1 and plane 2 and the press the bar "Get angle!" You get the angle in degree, rad, the cosine and sine and the direction of the line of intersection of the plane. This applet uses Geometric Algebra.
Tested with Netscape 7.02 (Java 2) and IE 6.0. The source code of this applet is available for download under the GNU Lesser General Public License. You can also download Dihed (zip compressed, 29k) as standalone Java application. Just unzip it and check the included Readme file.
