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.
An excircle or escribed circle [2] of the triangle is a circle lying outside the triangle, tangent to one of its sides, and tangent to the extensions of the other two. Every triangle has three distinct excircles, each tangent to one of the triangle's sides.
A mathematical symbol is a figure or a combination of figures that is used to represent a mathematical object, an action on mathematical objects, a relation between mathematical objects, or for structuring the other symbols that occur in a formula. As formulas are entirely constituted with symbols of various types, many symbols are needed for ...
The large triangle that is inscribed in the circle gets subdivided into three smaller triangles, all of which are isosceles because their upper two sides are radii of the circle. Inside each isosceles triangle the pair of base angles are equal to each other, and are half of 180° minus the apex angle at the circle's center.
The Eye of Providence can be found on the reverse of the Great Seal of the United States, as seen on the U.S. $1 bill, depicted here.. The Eye of Providence or All-Seeing Eye is a symbol depicting an eye, often enclosed in a triangle and surrounded by rays of light or a halo, intended to represent Providence, as the eye watches over the workers of mankind.
The incircle is the circle that lies inside the triangle and touches all three sides. Its radius is called the inradius. There are three other important circles, the excircles; they lie outside the triangle and touch one side, as well as the extensions of the other two. The centers of the incircles and excircles form an orthocentric system. [26]

The commonly-used diagram for the Borromean rings consists of three equal circles centered at the points of an equilateral triangle, close enough together that their interiors have a common intersection (such as in a Venn diagram or the three circles used to define the Reuleaux triangle).
