To have a straight cut, press the Opt key before drawing a cut line. In order to snap the cut line to 45, 90 degrees and so on, hold down the Opt and Shift keys.

If you cut a closed path, paths of created objects will also be closed. The program will automatically add new path segments where they are needed.
