The Pytagorean Theorum says that in a right triangle, the sum of the squares of the length of the 2 sides (adjacent to the right angle) is equal to the squre of the hypotenuse.
A simplified version of this for construction workers is based on the fact that this formulation comes out with nice even numbers when any multiple of the ratio 3:4:5 is used (9+16=25).
Thus if a building is say 44 feet long by 40 feet wide, the lay-out would begin on the straight 44' side. a measurement of 33' from one end of it "eyeball close" to perpendicular would be pulled and an arc swung maybe 3-5 feet long at that measurement.
Then from the opposite corner of the 44' wall, a 55' measurement would be pulled to intersect with the arc just drawn. A string pulled from the origin of the 33' measurement through this intersection and on out to the 40" point would square these 2 walls to each other well within 1/4" tolerance.
Lay-out people will just as readily say "Let's pull a 3:4:5" as they will "let's square it up"

Where is the geometry used?
Geometry is used mainly in construction.
What are the advantage and disadvantage of builder's square method?
There are both advantages and disadvantages to using the builder's square method. One advantage is that it is a relatively simple method to use and can be easily learned by most people. Another advantage is that it is a versatile method that can be used for a variety of projects, including construction, remodeling, and repairs. However, there are also some disadvantages to using the builder's square method. One of these is that it is not always accurate, and this can lead to errors in your project. Additionally, it can be time-consuming to use this method, especially if you are working on a large project.

How long is 20feet?
Twenty feet is equivalent to 240 inches or approximately 6.1 meters. This measurement is often used in various contexts, such as construction, sports, and everyday dimensions. To visualize, it's roughly the length of a standard car or the height of a two-story building.
What is the meaning of plinth area?
Plinth area refers to the total area of a building measured at the floor level of the building's exterior walls. It includes all covered spaces, such as rooms, halls, and corridors, but typically excludes areas like balconies and open terraces. The plinth area is often used in real estate and construction to determine the floor space for various purposes, including pricing, valuation, and building regulations. It serves as a key metric in assessing the size and capacity of a structure.

In construction of a building what does delivery stand for?
Delivery is sometimes used to refer to the stage in building construction where the building is available to the user. This can be completion, or can be before completion of construction.
What is the census used for in government construction?
NACIS is the census that is used for government construction. This is used when building homes.
What is unitised building?
Unitised building refers to a construction method where pre-fabricated modules or units are manufactured off-site and then transported to the construction site for assembly. This approach enhances efficiency, reduces construction time, and minimizes on-site labor, as the units are often fully finished or close to completion before arrival. Unitised building is commonly used in projects like apartment complexes and hotels, where repetitive design elements can be standardized. This method also allows for improved quality control and reduced waste during construction.
How is glass used in building construction?

Does brick mean joisted masonry?
a home that has brick is still considered a frame building. since the construction method used has wooden frames, with a brick veneer finish on the outisde, it is ultimately considered a frame building.
Where is construction of triangles used?
In building slanted roofs.
What are construction cones used for?
Construction cones are used to keep people from accidentally interrupting construction. Without them there would be quite a few problems when building.
what is the best to construct a multiple storage building or a banglo?
