Biradially is an uncommon word that describes a structure or an arrangement that extends in two opposite directions from a center or axis in a radial manner. There are several synonyms to describe a similar arrangement, such as "radially symmetric," "bilateral," or "bilateral symmetry." Other synonyms include "dihedral," "bifocal," and "two-sided radial." These words suggest the concept of symmetry and balance between two sides, like the wings of a butterfly or the petals of a flower. Scientists and engineers often use these terms to describe the structural properties of molecules, crystals, and materials in biotechnology, optics, and nanotechnology.
