Trigonometry: Spherical Trigonometry:
“. . . If we start synergetically with whole systems such as spherical trigonometry then you avoid the concept of an edge and instead learn of the accommodation of surface and central angles. Then having both surface angles and central angles we discover that spherical trigonometry is always dealing with tetrahedra whose interior apexes are at the center of the system.”
