Rigid
Polygon

**A
Rigid Polygon** is a polygon that can only be rotated and
translated. Its shape cannot be altered.

It is drawn in the same way as an ordinary polygon: the
tool is selected and then at least three points which will be the vertices of
the polygon must be selected and then the first point is clicked again.

##
Vector
Polygon

**A
Vector Polygon** is a polygon where the first point presents the
origin (the position of the other points is calculated according to this point).

It can be drawn in the same way as a Rigid Polygon.

##
PolyLine

With the **PolyLine** tool a
polygonal line can be drawn.
