In Euclidean geometry any three points, when non-collinear, determine a unique triangle and simultaneously, a unique plane. In other words, there is only one plane that contains that triangle, and every triangle is contained in some plane. If the entire geometry is only the Euclidean plane, there is only one plane and all triangles are contained in it; however, in higher dimensional Euclidean spaces this is no longer true. The unique pattern of this Jay Austin Bowtie make it both fashion forward and classic style simultaneously. 100% silk seen here in the diamond shape.
