You can redefine the coordinate system of selected vertexes to work more conveniently with them. The coordinate system allows you to move the origin and/or to rotate XY axes. The redefined coordinate system may be also constrained to existing vertexes or to absolute coordinate system.

Vertexes selected for change of the coordinate system
Method of coordinate system redefinition
In previous step the coordinate center was selected (a corresponding vertex is marked with ‘0’). A vertex defining direction of X axis is being selected.
Selecting vertexes for constraint definition. If a vertex is selected and the vertex belongs to a group of vertexes with redefined coordinates, you cannot select vertexes with different coordinate systems – otherwise the constraints cannot be defined. In this situation, the not-selectable vertexes are redrawn in different colors.
Constraint distance is defined.
The vertexes were moved according to the newly defined constraint.
Another constraint is defined – this time for the right three vertexes. A new distance to the coordinate center is defined as shorter than the previous distance.
After performing the new constraint, vertexes were moved. Because one of them defines direction of X-axis from the previously redefined coordinate system, corresponding vertexes are transformed, too.
