Algebraic formulas for the Euler characteristic are applied to the topological study of the moduli spaces of planar polygons. In particular, a complete description of the moduli spaces of planar pentagons is obtained by using a computer algorithm for the calculation of the Euler characteristic of algebraic varieties. Bibliography: 17 titles.
