What is Sacred Geometry?
Thanks DL. I agree that the irrationals such as Pi and Phi are sacred numbers and found in nature. Although in a way all geometry is sacred in that it is eternal and unchanging. Consider the 5 Platonic solids as an example.The short answer is irrational. Or, to be more precise, irrationals. Pi and Phi are sacred numbers, yet are arguably better described as functions rather than numbers. The Golden Rectangle illustrates this in simple form, for example, as it employs the Golden Ratio. The Golden Ratio is regularly found in nature, from the structure of crystals and the spiral of the chambered nautilus to the patterns of spiral galaxies.

Also of note would be a study of Leonardo da Vinci's work entitled "Vitruvian Man."
