Two triangles in the mesh of a window (Dom of Utrecht)
A hollow and spherical triangle is in the mesh of a window, for example, a simple ornamental motif is often used to replenish the rest area where there is no room for a fishblade with a tote or other ornamental motif. On the other hand, she was very consciously used to realize a particular line-up. Often, these triangles provide no residual space, space to other elements of the trace. These hollow and spherically bent triangles were often used in combination with other ornate motifs and were used mainly in the Gothic traces of windows.
A triangle like this is to be transformed into threefold using three totals. Also see
