kig: an interactive geometry program for KDE


kig - an interactive geometry program for KDE


kig [-c, --convert-to-native [-o, --outfile filename]] [KDE Generic Options] [Qt Generic Options]


Kig is an application for interactive geometry. It is intended to serve two purposes:

To allow students to interactively explore mathematical figures and concepts using the computer;
To serve as a WYSIWYG tool for drawing mathematical figures and including them in other documents.

With this program you can do geometry on a computer just like you would on a blackboard in a classroom. However the program allows you to move and change parts of a geometrical drawing so that you can see how other parts change as a result.

Kig supports loci and user-defined macros. It also imports and exports both to and from foreign file formats including Cabri, Dr. Geo, KGeo, KSeg and XFig.

This application is part of the official KDE edutainment module.


App options, in a variablelist

-c, --convert-to-native
Do not show a GUI. Instead convert the specified file to native Kig format. The native Kig file will be written to standard output unless --outfile is passed.

-o, --outfile filename
Used with --convert-to-native to specify where to save the newly created Kig file. Not specifying this option, or providing a filename of - will output the file to standard output.


Kig was written by Dominique Devriese <devriese [at]>, Maurizio Paolini <paolini [at]>, Franco Pasquarelli <pasqui [at]>, Pino Toscano <toscano.pino [at]>, and others.

This man page based on the one prepared for Debian by Ben Burton <bab [at]>.
