You can do that very easily.
sage: polygon?
Returns either a 2-dimensional or 3-dimensional polygon
depending
on value of points.
For information regarding additional arguments, see either
polygon2d? or polygon3d?.
EXAMPLES:
sage: polygon([(0,0), (1,1), (0,1)])
sage: polygon([(0,0,1), (1,1,1), (2,0,1)])
The original poster was asking about having ONLY side lengths
specified, as far as I can tell.

The KIG website is not all that helpful, unfortunately - for instance,
the screenshots page is empty. Is the project still very active?
Geogebra has lots of excellent constructions, and hopefully someday
the Sage-Geogebra interface will be complete. For now, see for
instance http://www.slu.edu/classes/maymk/GeoGebra/SideSideSide.html ,
and it is pretty easy to get Geogebra to give you coordinates for
points.
