# General rule/algorithm for finding the points of a polygon, given only the lengths of the sides

I have a polygon and I only know the length of its sides, how would I go about figuring out what it's points are?

Assume that the first side starts from the origin $(0,0)$ and extends along the x axis to (length of side $(a, 0)$ ).

I realize that this is trivial for, say a triangle, but is there a rule that can be used for all polygons?
