"🛑THE 3-4-5 METHOD 🏗️
👉🏻 is an essential technique in the construction and civil engineering fields to accurately trace right angles on construction sites. Based on the Pythagorean theorem, it guarantees the orthogonality of structures, ensuring their stability and proper alignment.
Application of the 3-4-5 method:
1. Measurement: Starting from an origin point, measure 3 units along a reference line and mark this point.
2. Second measurement: From the origin point, measure 4 units perpendicularly to the first line and mark this point.
3. Verification: Measure the distance between the two marked points; it should be 5 units. If this is the case, the angle formed is a right angle.
This method is particularly useful for laying foundations, aligning walls, and verifying the perpendicularity of structural elements. It is simple to implement and only requires basic tools such as a tape measure.
For a visual demonstration of this technique, you can refer to the following tutorial:

By adopting the 3-4-5 method, construction and public works professionals can ensure the precision and quality of their projects, thus contributing to the durability and safety of infrastructures.
