Hello tiler people...

Quick question that may or may not stump you.

Have any of you used a 3-4-5 Triangle to set out a floor before?

I welcome anyone's adventures

Tileboy :-))

yes mate loads of times over the years

Yes I do all the time only way to do a floor IMO 4.5 mts x 6 mts x 7.5 mts and smaller if I cant get that size in the larger the better as it will be more accurate :Pete

120 x 160 gives 200 . Use a laser now! 2Balls

PJC, hi...

Thanks for your reply mate. Would you mind running me through your way of doing this. I have a good idea of how this works and I know it aint always necessary to do this but I would like to hear from other, possibly more experienced, tilers than myself...

Thanks mate...

3ft down 4ft across mesure between two points = 5ft (builders square)

I can´t find better words ! 2Balls

Essentially, a triangle which has the side-proportions 3-4-5, is a right-angled triangle.

You can use that to, for example, check if two walls are right angled to each other, by making marks 60cm (which is 3cmx20) and 80cm (4cmx20) away from their shared corner/angle, and then measuring between them. If the stretch between them is exactly 100cm (5cmx20), the corner is exactly 90 degrees. This is based on the pythagorean theorem.

in a long corridor, or just for the hell of it, you can also use 5-12-13 as well, this is also based on pythagoras theorem

Ah i get it now!

I wasn't sure what you were using the triangle for, but now i see what you're saying. Think i'd always have the tiles running at 90° to the main doorway anyway, so not 100% sure if i'd need this technique. Can't hurt to have it stored away though right?

your welcome mate couldn't tile a floor without it

the square of the hypotenuse of a right angle triangle is equal to the sum of the squares on the other two sides!! go on guys and girls, get your calculators out!!

Okay - someone has to post it


" Once upon a time in an Indian village, there lived three squaws. Two squaws had young sons who were very overweight. The first squaw, whose son weighed 150 pounds, always placed her son on a bear hide near a pine grove; the second squaw, whose son also weighed 150 pounds, put her son on a moose hide in the shade of a large oak tree; but the third squaw, who was expecting the birth of her first son, always rested on a hippopotamus hide beside a bubbling brook. Her weight? 300 pounds!

To this day, mathematicians give credit to these women and their children for proving the Pythagorean Theorem, because you see: The squaw of the hippopotamus is equal to the sons of the squaws of the other two hides "

ouch!

frogeye - obvious joke provider

Ha ha....That is awesome beyond atoms mate. Well done!!!


Thank you guys, all for joining in today...

My personal preference is to use my trusty cross line laser, gives acurate readings on walls and floors.

but what happens if it breaks , God forbid!!

my old man is a brickie and my best mate a joiner,if i dont use this then i'm not doing my job properly according to them!!!

There are LOADS of uses for this technique, especially if you don't always carry a right-angle laser with you, or if you hate dry laying.

I once met a tiler who carried two balls of string with him. First he'd mark the centre of the side of a surface he wanted the tiles to run from, and then he'd make another mark 60 or 120cm to the left or the right of that mark. Then he'd fasten a nail at each mark. Then fastened a ball of string to each. One of the balls of string had knots at 80cm intervalls, and the other had knots at 100cm interwalls. Then he'd just converge the nots, make a couple of marks, and then make a guide line with his chalk hog.

Took him about three minutes.

The power of the 3-4-5 triangle is that you can check if sides of a surface are right angled to each other relatively fast. If a side is out by two centimetres, you may not notice it until it's to late. The 3-4-5 triangle method makes that easy to avoid.

the most simple and effect method in my opinion. Whether setting out for tiles, stud walls pr any other task

i use it all the time when setting a floor out one of the first things things i was taught

3 4 5 trangle.

The square of the hypotinuse = the square of the opposite plus the square of the adjacent.

Hence 3x3 = 9, 4x4 = 16 and 5x5 = 25

Pythagoras.

As Pete says, the units you use is immaterial, provided you are consistent.

I use a stanley collapsible square

Isn't geometry useful

I use this from time to time when I need to.

Another useful thing is to measure from corner to corner both ways to see if things are square.

Laser for me. Job done in seconds not minutes.
