the program will know the types of geometry you are working with in the file, based upon the type you digitize into it.
if you use v.digit and add "lines", it will be aware of lines and report them with v.info or after it is built for topology when exiting v.digit. If you add boundaries, it will expect a centroid to be in the boundary, and the boundary to be closed. It turns green when it is 'proper'. when you have a boundary and a centroid, and it exits/builds, it will report the areas, which will be your polygons.
