For the benefit of those who may have forgotten their geometry days, the Forty-Seventh Problem is here simply stated; in any right triangle, the sum of the squares of the two sides is equal to the square of the hypotenuse. This is demonstrably true regardless of the length of either side. But in the Problem as diagrammed in the lodge, and for simplicity’s sake it is usually shown with sides the proportions of which are as three, and four units when the hypotenuse, or longest side of the triangle will be as five units. If one draws on paper a line three inches long, and at right angles to it , and joined to one end, a line four inches long, then the line connecting the two ends will be five inches long when the angle is a perfect right angle, or one of ninety degrees. The square of 3 is 9. The square of 4 is 16. The sum of 9 and 16 is 25. The square root of 25 is 5.
