Therefore, a pentagon cannot appear in any tiling made by regular polygons. l'UE est entrée depuis le scrutin européen de juin dernier pour sensibiliser les autres institutions à ses recommandations. In contrast, the regular pentagon is unique up to similarity, because it is equilateral and it is equiangular (its five angles are equal). A self-intersecting regular pentagon (or star pentagon) is called a pentagram.

A regular pentagon has five sides of equal length. {\displaystyle d_{i}} [16] As of 2020[update], their proof has not yet been refereed and published.

From trigonometry, we know that the cosine of twice 18 degrees is 1 minus twice the square of the sine of 18 degrees, and this reduces to the desired result with simple quadratic arithmetic.
