👉 In geometry, a rhombic dodecahedron is defined as one of the five Platonic solids. It has 12 equilateral triangles as faces and 6 square faces. Each face is a regular polygon with an equal number of sides (6) and each vertex is connected to two other vertices by edges. This means that it's a 3D solid with six triangular faces, one hexagonal base, and twelve edges.
