Golden Polyhedra Starting from a golden rhombus, you can build a 30-faced rhombic triacontahedron that serves as the foundation for creating a golden icosahedron and a golden (Bilinski) dodecahedron. From there, two types of six-faced polyhedra known as golden rhombohedra can be derived: the acute form and the obtuse form. These unique shapes appear unusual on a screen but fit together perfectly in your hands. In addition to the process described here, there are other ways to create these mathematical wonders. However, this is the method I chose to follow. Simple or complex, children should have the opportunity to explore these beautiful mathematical structures and develop an appreciation for mathematics. The intricate connections between them are a testament to their beauty. Two sizes of golden rhombohedra are included: 25mm and 50mm. Instructions for Playing Combine two acute ones with two obtuse ones to form one golden dodecahedron. Join ten acute ones with ten obtuse ones to create one golden rhombic triacontahedron.
