Borromean rings. In mathematics, the Borromean rings[a] are three simple closed curves in three-dimensional space that are topologically linked and cannot be separated from each other, but that break apart into two unknotted and unlinked loops when any one of the three is cut or removed. Most commonly, these rings are drawn as three circles in ...

Commonly, designs are based on circles centered on triangles (with the simple, two circle form named vesica piscis) or on the square lattice pattern of points.

It appears on a variety of objects from the archaeological record of the ancient Germanic peoples. The term valknut is a modern development; it is not known what term or terms ...
The vesica piscis is a type of lens, a mathematical shape formed by the intersection of two disks with the same radius, intersecting in such a way that the center of each disk lies on the perimeter of the other. [1] In Latin, " vesica piscis " literally means "bladder of a fish", reflecting the shape's resemblance to the conjoined dual air ...
Among hunters, a collection of three hares ("a brace and a half" or tierce)—or three creatures of any kind, especially greyhounds, foxes, bucks—is called "a leash ".

The geometric designs in Islamic art are often built on combinations of repeated squares and circles, which may ...
