Summary
The ancient Pueblo people built round ceremonial chambers at Chaco Canyon to mark the natural cycles of solstice and equinox. Like astronomers today, they knew the circular shape was ideal for tracking the progression of the Earth throughout the year. This program uses ancient structures to help define properties of circles, arcs, chords, secants, and central and inscribed angles. The video explains why the Colosseum is shaped like an ellipse instead of a circle, which would have been easier for the Romans to build. The Pantheon, with its round oculus and circular dome inside an arched ceiling, is also examined.
