The 3, 4, 5 method.
This is known as the Pythagorean theorem or Pythagoras' theorem is a fundamental relation in Euclidean geometry between the three sides of a right triangle. It states that the area of the square whose side is the hypotenuse is equal to the sum of the areas of the squares on the other two sides. Complicated neh?
In construction practice this is used to makesure that two sides (two walls) bisects each other where they meet, meaning the two walls form a 90° at the corner they intercept.
How this is archived is mind blowing as it doesnt require any calculations. This is how how the 3, 4, 5 method works.
Step 1
Using the corner where the two walls will biceps as reference, measure 4 meters on either side and mark it off.
Step 2
Measure 3 meters from the reference of second wall and mark it off.
Step 3
Now, measure the distance between the two points you have marked off. If the distance is not 5 meters than the two walls do not form a 90° where they intercept, and some adjustments have to be made.
