How to Check 90° Corner Using the 3-4-5 Triangle Rule. What is the 3–4–5 method? It comes from the Pythagorean theorem: 3^2 4^2 = 5^2 So any triangle with sides 3 units, 4 units, and 5 units will always have a perfect 90° angle. ⭐ 2. How it is used at site? At the building corner, workers measure: One side = 4.00 m Other side = 3.00 m Diagonal = 5.00 m If the diagonal equals exactly 5 m, the angle is correctly 90°. The top of the image shows this clearly: Left wall = 4.00 m Right wall = 3.00 m D

3-4-5 method in construction To check a right angle: If you have a corner that you want to be exactly 90 degrees, measure (3) units along one wall and (4) units along the other from the corner point.Verify the angle: If the distance between your two marks is exactly (5) units, the corner is a perfect right angle.Applications: This method is used to ensure the accuracy of foundations, walls, and other structures, and is crucial for preventing errors that can compound over distances. #civilenginee
