+<h2>Quadrangle parameters</h2>
+
+<b>Quadrangle parameters</b> is a hypothesis for
+Quadrangle (Mapping), which allows using this algorithm for meshing of
+triangular faces.In this case it is necessary to select the <b>Base vertex</b>
+used as a degenerated edge.

+
+This hypothesis can be also used to mesh a segment of a circular face.
+Please, consider that there is a limitation on the selectiion of the degenerated
+vertex for the faces built with the angle > 180 degrees (see the picture).

+\image html hypo_quad_params_2.png "3/4 of a circular face"
+
+In this case, selection of a wrong vertex for the <b>Quadrangle parameters</b>
+hypothesis will generate a wrong mesh. The picture below
+shows the good (left) and the bad (right) results of meshing.
