What is the 2 4 6 method when putting up a wall or how can you square a wall with nothiing to go by?

Answer 1

Actually, it's the 3, 4, 5 method. If you create a right angle triangle with the two sides closest to the right angle being 3 and 4 units (inches, feet, meters, miles... whatever) the "opposite" (opposite to the right angle) length will be 5 units. If you know much about math, you can use the Pythagorean theorem to calculate the sides of the triangle. The Pythagorean theorem states: "The square of the hypotenuse is equal to sum of the squares of the other two sides. If this is true, then the square of 3 plus the square of 4 will equal to the square of 5. Is that true? Three squared = 9. Four squared = 16. 16 + 9 = 25 which equals the square of 5. If you have a known right angle triangle, you can use it to square a wall, floor or just about anything else. Measure 3 and 4 units on what is SUPPOSED to be a right angle, then the hypotenuse can be measured and when it is 5 units, the wall, floor or whatever is, by definition, square. simply use the line where you are going to put the wall. where this line intersects or ends at another line{wall] measure from this point 4 feet and make a mark . then measure 2 feet out from starting point and mark a slight arc roughly at a right angle to first line then measure from the 4 foot mark 6 foot to the 2 foot mark and make a slight arc and where the 6 foot and the 2 foot marks intersect will be a perfect right or square angle. for big rooms use 4-6-8 or 8-12-16. I failed algebra but have built many a house using this method.
