Geometric patterns discovered in ancient Pueblo buildings

The hidden patterns of America's first temples: Ancient Pueblo people built geometric structures despite having no written language or number system --- Hundreds of years ago, the ancient Southwestern Pueblo people built complex geometric structures with near-perfect accuracy, creating equilateral triangles, 45-degree right triangles, and even the ‘Golden rectangle.’ And, they did it all without writing any numbers down. At the Sun Temple archaeological site in Colorado, constructed around AD 1200, researchers have discovered a slew of sophisticated shapes that are still familiar today, revealing architectural ‘genius’ that they say would be almost impossible to replicate. | Daily Mail
