Solvimages[1]ing the 47th Problem

Article written by Mike Fox, owner of Fox Jewelry; the leading marketer of Masonic Rings and other fraternal rings.

The forty-seventh problem of the first book of Euclid is that: in any right-angled triangle the square which is described upon the side subtending the right angle is equal to the squares described upon the sides which contain the right angle. It was  discovered by Pythagoras while in Egypt and was taught to him by the priests in that country. It was solved by Euclid, the Father of Geometry. It is a symbol of the production of the world by the prolific powers of the Creator. The 47th Problem of Euclid, also called the 47th Proposition of Euclid, or the Pythagorean Theorem, is represented by what appear to be 3 squares.  “In any right triangle, the sum of the squares of the two sides is equal to the square of the hypotenuse.” (The hypotenuse of a right triangle…which is the longest “leg”…or the 5 side of the 3:4:5).

3:5:7:  These are the steps in Masonry.  They are the steps in the Winding Stair which leads to the Middle Chamber and they are the number of brethren which form the number of Master Masons necessary to open a lodge of: Master Mason:  3 Fellow Craft:  5 Entered Apprentice:  7 Master Masons.

The essence of the Pythagorean Theorem (also called the 47th Problem of Euclid) is about the importance of establishing an architecturally true (correct) foundation based on use of the square.

The 47th Problem of Euclid is the mathematical ratio (the knowledge) that allows a Master Mason to: “Square his square when it gets out of square.”
