It can be 3/4/5mm, 3/4/5 feet, 3/4/5 metres or 3/4/5 miles!Okay, you've got me this is Pythagorus' theorumReally easy though!To create corners, we use the 345 rule derived from the Pythagorean theorem of basic geometry A 2 B 2 = C 2 This means the square of the hypotenuse of a right triangle is equal to the sum of the square of both legs Getting away from the geeky math stuff, it simply means that if you measure 3' out from the corner in one direction, and 4' out in the other direction, the line
Remember in high school when the teacher made you try to understand the Pythagorean theorem? This is shown as A squared B squared = C squared and is known as the 345 rule in constructionIt is also known in the construction industry as 345, meaning the if the length is 3 (squared = 9) and the width is 4 (squared = 16) then the diagonal is 5 (squared = 25) Verification is true in that 9 plus 16 is 25, of which the square root is 5
When I use this method to put down two base plates I fix one plate in place and move the other round until I get a perfect '5' and then fix that too The reason this works is because of the ancient check for square formula Pythagorus theorum That is to say 3 squared, plus 4 squared345 rule for squaring For squaring up a deck, foundation, or anything else that needs to be square, use the 345 rule The best place to start is in one corner of the layout The corner should be a right angle with two legsAnswer (1 of 3) This is an old, timetested "trick" often used by Carpenters, Builders, Excavators, Surveyors, et al The numbers relate to the definitive pattern of a RIGHT trianglethat being a triangle that has a 90 degree angle between adjacent sidesand simply indicates the lengths of
The rule is a basic rule of geometry called the Pythagorean Theorem A squared plus B squared equals C squared, thus 3*3 4*4 = 5*5 (916=25) Search for Articles on Acme How ToSolve limits stepbystep \square!Here is the rule when a and b are not negative And here is how to use it Example simplify √12 12 is 4 times 3 √12 = √(4 × 3) Use the rule √(4 × 3) = √4 × √3 And the square root of 4 is 2 √4 × √3 = 2√3 So √12 is simpler as 2√3 Another example Example simplify √8 √8 =
Okay, you've got me this is Pythagorus' theorumReally easy though! Do 144 (what's in the parentheses) first, which gives you 34 You would then change that into 34 squared, and to make it a fraction, you would do 34 over 10 (34/10)^2 Divide both the numerator and the denominator by 2, because it isIf you are building your own paving stone patio, the second most important thing after getting a good base is making sure it's square In this video, we'll s
In a right angled triangle the square of the two smaller sides added together is thWe have established this standard of clear and concise four square game rules over a decade and more of court time and shared experiences These standards make it possible to learn and enter play faster, have more in common with other communities playing the game, and create a jumping off point for players to experiment and improvise The second way is to use simple geometry You can do this without using a calculator if you use a 345 right triangle If you have a right triangle with sides of 3 units and 4 units, the diagonal side will be 5 units long So start at the corner you want to check, make a mark along one side which is 3 units out (use feet or even yards or

Pythagorean Triple 345 is an example of the Pythagorean Triple It is usually written as (3, 4, 5) In general, a Pythagorean triple consists of three positive integers such that a 2 b 2 = c 2 Other commonly used Pythagorean Triples are (5, 12, 13), (8, 15, 17) and (7, 24, 25) So carpenters and concrete formers will often employ a 345 triangle technique to ensure accurate 90 degree angles The technique simply requires that a person create a triangle in the corner of the lines that are to be square (90 degrees) to each other The triangle must have one side (leg) that is 3 feet long, a second side that is 4 feet long and a third side that is 5 feet longHow to Use the 3 4 5 Rule to Build Square Corners One of the challenges when creating corners is getting them square While your room doesn't need to be perfectly square, it's best to get corners as close to 90 degrees as possible

Pro Tips How To Square a Large Project Using the 345 Rule Whether you are tiling a floor or laying out a foundation, measuring for square is an important technique to ensure that and area is square A carpenter's square or framing square just isn't large enough to square two long lines To make certain that two lines are 90° to each other, use the simple 345 techniqueThe equation for area of a 3 4 5 triangle is given as Area = 1 / 2 bh This becomes area = 1 / 2 (3)(4) = 6 when it is a true 3 4 5 triangle If the triangle is scaled from the ratio by a common factor, we can multiply 6 by that common factor to get the area3 Multiply the length by the width to calculate the area of your space in square metres 4 Divide the space (calculated in square metres) by four to calculate the maximum number of people allowed 5 Consider items and objects that may impact the total free space of the premise such as tables and counter tops See example below
And with the 345 triangle you can find your right angles without any complicated calculations How to Use It Pick one leg of your project and measure out 3 feet from the corner Put a mark on the board at the 3 feet point Now, measure the adjacent board from the same corner to 4 feet and put a mark there Then, measure the distance between the two marks If it is 5 feet,Other Using the 345 method for squaring corners will help ensure your corners are square To create corners, we use the 345 rule from basic geometry 4 feet This means the square ofthe hypotenuse of a right triangle is equal to the sum ofthe square of both legs = (5)2 9 16 25 Getting awayfrom the math stuff it simply means that ifyouBecause 3 ^2 4^2 = 9 16 = 25 and 5^2 = 25 and 25 = 25
The Mathematics Behind It The Pythagoras Theorem says In a rightangled triangle, the square of a (a 2) plus the square of b (b 2) is equal to the square of c (c 2 ) a 2 b 2 = c 2 Let's check if it does work 3 2 4 2 = 5 2 Calculating this becomes 9 16 = 25 Yes, it works ! If you use the 345 method as a technique to square deck corners, you will have to make some adjustments in case the longest leg is off What you need to do is moving one side, maybe move the other two leg in or out 3 or 4 feet 345 Rule To Ensure Square Layouts Carpenters and builders often use the 345 method for squaring corners and ensure that the projects they are
