It is geometrically proven that the angle bisectors, the perpendicular bisectors, the medians, and the altitudes all meet at a point either inside or outside of a given arbitrary triangle. However, for an equilateral triangle all these meeting points come to a point at a single location of space-time inside the triangular universe.

For the angle bisector, the meeting point is the center of an inscribed circle. For the perpendicular bisector, the meeting point is the center of a circumscribed circle. For the medians, the meeting point is the centroid of the triangle. The centroid is also known as the center of mass or center of gravity. For the altitudes, the meeting point is simply known as the orthocenter. Since the perfect symmetry of space-time must be a simple pattern of tessellation, the local minimizing pattern of tessellation must be an equilateral triangle. The local maximizing tessellation pattern can be that of a square. Within the equilateral triangle can be found the special 30°-60°-90° triangle and within the square can be found the 45°-45°-90° special triangle. Therefore, to a point the entire universe can be described concisely by these min-max patterns, one for bosons and one for fermions.
