# How important is the Pythagorean theorem?

## Pythagorean Theorem Helps Carry Out Modern Building Projects

* Perfect square corners are crucial in any building project. No matter the size, this rule must be precisely followed.* Whether it is a jewelry box, a birdhouse, a closet, or even the layout of a backyard patio, the woodworkers and landscape experts have to find a way to generate an accurately square shape of the corners. Luckily, advanced technologies are not necessarily required for this Instead, they use an ancient mathematical principle.

### A Simple Mathematical Principle That Works Wonders

Probably something triggers in your mind when you hear: a2.132=c2. Something vague, which was mumbled once by the math teacher. Well, in fact that was the Pythagorean Theorem, which is a principle saying how to calculate the measurements of a right triangle. The Greek mathematician was only the one who coined officially the rule. **In reality, it was applied on many ancient building projects, centuries before it was proven on practice by Pythagoras.**

In the modern language of building workers, this term turned into the3-4-5 method. It describes a proportion, used to achieve perfect square layout lines and corner angles. How the 3-4-5 Method Works

### This is how you square up a corner, using the 3-4-5 method

**These numbers are not random at all.** They define a proportion, and sometimes the figures can alter, depending on which unit of measurement is used. *3 Stands for 3 inches*, you need to measure from the corner. It is important to make a mark in that point. *After that, switch to the opposite side of the corner, and measure 4 inches.* *Make, also a mark, and join it with the second mark, to identify the distance between them. If it is 5 inches than the corner is perfectly square.*

**The 3-4-5 method is explained very well by the Pythagorean Theorem. **Replace the letters with the numbers, do the proper calculations, and you will find out that the equation is true. It Is Not Always 3-4-5

As it was mentioned, the 3-4-5 line can become 6 8 9, or 9 12 15.** The proportion is what matters, indeed. In fact, a lot of measure units can be used to express the proportion.** You can use inches or centimeters, when you work on a birdhouse,or digging a pool in your backyard, use bigger units as meters and feet. For example, when you establish the foundation of a deck layout, you check the level of squareness of its corner, with the 3-4-5 proportion, measured in feet. Also, it works with the building of a fence around the house. **An important aspect in working with this method, is the ability to do the adjustments, when the third leg does not show 5, and fails to generate a square shop. Take up your time and be patient, until you get the needed result.**

**On the whole, the 3-4-5 method is a science-proven tool that helps accomplish building projects with great precision and beauty.** No matter if you craft a tiny jewelry box, or go big with a commercial building foundation, the rule can be freely applied with not a bit of hesitation, and with high consideration to proportion standards.
