The practice of the polygonal methods in describing the spatial arrangement of particles is explained in detail, namely momentum analysis, order statistics and parametric estimation of the probabilistic distribution, all in the relation to the cell areas of the Voronoi tessellation generated by the reference points of the particles. The polygonal approach is then applied to four samples - TEM projections of thin foils of an aluminium based dispersed alloy with quasiglobular particles. The main advantages of the method are stressed: reliable characteristics of the arrangement can be obtained on the basis of relatively small samples and without the accurate knowledge of the thin foil thickness. Moreover, the sensitivity is higher in comparison with more standard approaches (e.g. quadrat counts).
