What happens here

The ultimate objective of layout and squaring is to achieve perfectly 90-degree corners and parallel walls for the structure. The most reliable method for achieving a true 90-degree angle is the 3-4-5 method, which is based on the Pythagorean theorem (A² + B² = C²). This method involves measuring specific distances along two intersecting lines and then checking the diagonal measurement between those points. The creator explains that once one corner is accurately squared using this method, it becomes easier to pull parallel marks for the remaining sides.

find that your line isn't square, you can move to square up your lines. The objective is to get 90° corners and parallel walls. The first most reliable method is a 3-4-5 method or the Pythagorean theorem. You can also do this as 6-8-10, 12-16-20, or any variable of 3-4-5. After you square one corner, it's easy to pull parallel marks off of that corner. To accomplish the 3-4-5 method, you need to measure from
