SUMMARY

The discussion centers on the hypothesis that the builders of Stonehenge utilized Pythagoras's Theorem, specifically the relationship A² + B² = C², in their construction techniques. The Telegraph article referenced highlights the presence of right triangles in various iterations of Stonehenge, suggesting an understanding of geometric principles. However, skepticism exists regarding whether the builders had formal knowledge of this theorem or simply recognized practical applications of right triangles, such as the 3-4-5 triangle, without documented calculations.

PREREQUISITES
  • Basic understanding of geometry, specifically right triangles
  • Familiarity with Pythagorean Theorem and its applications
  • Knowledge of ancient measurement systems, particularly base 60
  • Awareness of archaeological methods used in studying historical structures
NEXT STEPS
  • Research the historical context of the Pythagorean Theorem in ancient civilizations
  • Explore the significance of the 3-4-5 triangle in construction and architecture
  • Investigate ancient measurement systems, focusing on Babylonian mathematics
  • Examine archaeological techniques for analyzing ancient structures like Stonehenge
USEFUL FOR

Historians, archaeologists, mathematicians, and anyone interested in the intersection of ancient engineering and mathematics will benefit from this discussion.

Here is an article from The Telegraph about triangles in older versions of Stonehenge.
(The layout was revised several times).
There are several right triangles referred to that are taken as understanding Pythagoras's theorem.
The article has drawings.

Not sure I buy that they knew A2 + B2 = C2 rather than just knew things like a 3,4,5 triangle has a nice useful right angle since they haven shown the builders calculations.

They give us a "base 60" math a la the Babylonians, and I'll buy into the Pythagorean story, otherwise...
