Pythagoras theorem

[Time's Ran Out]

5x5 + 12x12 = 13x13
25+ 144 = 169

The sum of the squares etc.

John, how would you do the arcs ? I'm thinking , ping a chalk line then measure 4, then do the arcs using a string and pencil or drill hole through tape measure and anchor it?.... Hope you follow my description

John once more you put things better than I do.:lol:

Phil, I know this stuff is second nature to a few of you on here, I'm just trying to figure out the exact way you would put it in to practice, I understand now using arcs.

I'm sorry but i am still slightly confused. Maths is not my strong point! I can see the principle but not sure when to use it. Would you start with pinging a chalk line in the point of the room where you normally would then measure off this at the point where you need the tiles to lead into another room (for example). I would really love to get this mastered and i'm nearly there, i think :sofahide:

Thanks all

Mark if you are trying to get a 90 degree angle having found a centre line, then measure 3 ft/ 3m or 3 anything, you then measure 4 ft/4m along that line when you get 5ft/5m to intersect that is 90 degrees. Not the best explanation, but it is all I can do.

always do a 3-4-5 to double check chalk lines

Thanks phil, I do understand, the only slightly cloudy bit now is how you would draw the arcs?, I'm thinking a tape measure with 2 small holes drilled 4 and 5 feet apart, one for anchoring with a small nail then the other for putting your pencil through.... Maybe I'm over engineering this lol

It's obviously easier if there are 2 of you but a tape, string or staff with a masonry nail on the points works for me!

I use 3 4 5 everytime on big floors, old habits die hard.

I used to use the staff with masonary nails method for many years. I still would on larger floors.
