The tetractys. The tetractys (Greek: τετρακτύς), or tetrad, [1] or the tetractys of the decad [2] is a triangular figure consisting of ten points arranged in four rows: one, two, three, and four points in each row, which is the geometrical representation of the fourth triangular number.
Greek letters are used in mathematics, science, engineering, and other areas where mathematical notation is used as symbols for constants, special functions, and also conventionally for variables representing certain quantities. In these contexts, the capital letters and the small letters represent distinct and unrelated entities.
Valknut variations. On the left unicursal trefoil forms; on the right tricursal linked triangle forms.. The valknut is a symbol consisting of three interlocked triangles.It appears on a variety of objects from the archaeological record of the ancient Germanic peoples.
The symbol is also sometimes used by Wiccans, White Witches, and some New Agers to symbolise the Triple Goddess, or as a protective symbol.

The Borromean rings have been used in different contexts to indicate strength in unity. [14] In particular, some have used the design to symbolize the Trinity. [3] A 13th-century French manuscript depicting the Borromean rings labeled as unity in trinity was lost in a fire in the 1940s, but reproduced in an 1843 book by Adolphe Napoléon Didron.
Triangles constructed on the unit circle can also be used to illustrate the periodicity of the trigonometric functions. First, construct a radius OP from the origin O to a point P(x 1,y 1) on the unit circle such that an angle t with 0 < t < π / 2 is formed with the positive arm of the x-axis. Now consider a point Q(x 1,0) and line ...
Lai Zhide's design is similar to the gakyil (dga' 'khyil or "wheel of joy") symbols of Tibetan Buddhism; but while the Tibetan designs have three or four swirls (representing the Three Jewels or the Four Noble Truths, i.e. as a triskele and a tetraskelion design), Lai Zhide's taijitu has two swirls, terminating in a central circle.
