As I mentioned in a post somewhere else in the Brew Cabin, I've been working on a simple drawing to encapsulate as many as possible of the geometric terms we use in the paving installation trade.
The page is now uploaded
I've some other bits and bats to add, especially relating toi right-angled triangles and every schoolboy's favourite Greek, Mr Pythagoras, but that will have to wait until I have more time...hopefully before the next Christmas break!

very good boss
one thing that has always helped me is pi
2 pi R for the circumference of a circle
and piR squared for the area
I remember doing it at school but it works in real life and makes pricing easier
LLL 
ps
pi is roughly 3.142

you use the above formula without knowing it sean, when you place your knife into your cow heel pie in the direction your mouth is facing and then at 30 degrees to the left - this is called a piece of pi

looks good tony. is the 3,4,5 method anywhere on the site. i find it is an easy way of getting right angles.

I did think about including area and circumference equations but worried that it might be patronising. However I suppose that, if the page includes definitiuons for radius and diameter, Pi should probably be mentioned...I'll add it to me list
(Bloody html won't print a Pi symbol, which should be Π or Π - bugger!)

It's obviously not worked for you, Mick!
I think it might be the Brew Cabin software which doesn't print certain html entities for security reasons. All three options (Π Π Π), plus π for a lower case pi are working on normal pages. It's just the Brew Cabin being awkward.

I wonder what else doesn't work?
