The 3-4-5 the builders use to square a corner
engineering
A triangle with sides 3, 4, 5 is exactly right-angled — 3² + 4² = 5². It is why a knotted rope or a framing square gives a true corner without a protractor. Worked & sealed by the engine — 3² + 4² = 5² → a true right angle. [HOLDS; open the seal to re-check.]
