METHOD SQUARE
3-4-5 METHOD SQUARE is a useful method in the fields of construction and civil engineering to accurately track right angles on construction sites. Based on the Pythagorean theorem, it ensures the balance of structures, ensuring their stability and correct alignment. Application of the 3-4-5 method: 1. Measurement: Starting from the original point, measure 3 units to the reference line and mark this point. 2. Second measurement: From the original point, measure 4 units to the first line and mark this point. 3. Verification: Measure the distance between the two marked points; it should be 5 units. If so, the angle formed is a right angle. This method is especially useful for laying foundations, connecting walls, and verifying the perpendicularity of structural elements. It is easy to perform and requires only basic tools such as a tape measure. For a visual demonstration of this technique, you can refer to the following tutorial: 3-4-5 method for drawing perpendiculars i...
