Re: Special cases
"The Egyptians beat Pythagoras to it; they used 3:4:5 for land surveying. Heck, I used it a lot when building my home 14 years ago."
When we moved into our home some years ago after my parents had dies I wondered what became of the 3:4:5 wooden triangle my dad made to set out the walls when he built the house. A year or so ago I found it propped up against a boundary wall when I was cutting back a holly. The joints attaching the hypotenuse had rotted but I still have the right angle.
