Polygons are closed plane figures formed by three or more line segments. If a figure is open or curved, it cannot be considered a polygon. Concave polygons have at least one diagonal that does not pass through the interior of the polygon; all of the diagonals in a convex polygon are contained within the figure. Equiangular polygons have all angles congruent; equilateral polygons have all sides congruent. (02:58)

Chelated fluoroboron cations : synthesis and multinuclear nmr studies
The preparation of chelated difluoroboron cations (DD)BF2+, where DD is a saturated polydentate tertiary-amine or polydentate aromatic ligand, has been systematically studied by using multinuclear solution and solid state nuclear magnetic resonance spectroscopy and fast atom bombardment mass spectrometry. Three new methods of synthesis of (DD)BF2+ cations are reported, and compared with the previous method of reacting a chelating donor with Et20.BF3. The methods most effective for aromatic donor
