Kig is an interactive mathematics software for learning and teaching geometry. It allows to explore mathematical figures and concepts using the computer and also can serve as a drawing tool for mathematical figures. Constructions can be made with points, vectors, lines, and polygons and all elements can be modified directly by using the mouse. Kig helps teachers and students to make conjectures and to understand how to prove geometric theorems.
For versions of Ubuntu between 14.04 LTS (Trusty Tahr) and 15.10 (Wily Werewolf), as well as Ubuntu flavours that don’t include snap by default, snap can be installed from the Ubuntu Software Centre by searching for snapd.
Alternatively, snapd can be installed from the command line:
sudo apt update
sudo apt install snapd
Either log out and back in again, or restart your system, to ensure snap’s paths are updated correctly.
