Knowledge about polygonsThis Demonstration shows a pentagon constructed using a straight edge and compass given the length s of one side. The construction uses five circles, each with radius s. All five sides are equal but the pentagon is not regularComponente Curricular::Ensino Fundamental::Séries Finais::Matemátic
