The triangle has been used throughout the ages by different craftsmen in all manner of occupations and is a common object in all our daily lives in one form or another.
It is used extensively in the Craft, Holy Royal Arch and other degrees of Freemasonry and is usually not given the recognition that it deserves.
A triangle is described as a geometric figure composed of three non-linear points, which are called vertices, with three straight lines joining the points.
