The 47th Problem of Euclid or Pythagorean Theorem

In this discourse, MW William Talbott “Terry” Ellison, Jr. explores the significance of the 47th problem of Euclid, also known as the Pythagorean Theorem, within Freemasonry. Although often overlooked, this geometric principle holds immense importance in mathematics and applied sciences. Ellison clarifies that while Pythagoras conceptualized it, Euclid provided the mathematical proof. The theorem, A² + B² = C², serves as the foundation for geometry and essential applications in surveying, engineering, and astronomy. Demonstrating its practicality, Ellison illustrates its use in construction, surveying, and even astronomical calculations. He emphasizes the symbolic connection between Geometry, the All-Seeing Eye, and moral teachings in Freemasonry.
