double the area, find two factors that multiply to equal it, these are your two short sides, then pythag to find the hypotenuse.
I hate maths, i really really hate maths.
We all know or at least should know that Pythagoras, the ancient Greek Philosopher and Mathematician ( 570 - 495 BC ) proved the relationship between the three sides of a right angled triangle,..the square of the hypotenuse being equal to the sum of the squares of the remaining two sides.
But what if we don't have this information,...let us say we know the area..'A' and perimeter..'P' of a right angled triangle. Can we still determine the length of the hypotenuse?
Can you derive an expression for 'h' using only 'A' and 'P'.?

To brainy question threads in one night from one user?
What is it mate, homework due today?![]()
Are you trying to get us to do your homework for you?
After all of that you should have the top and bottom half of your lawn mower joined together.
Hi,
Google should give you some thing. Link
cheers

As an example you might have a geometrical problem where the distance between two points if required and another distance is given. Drawing a scale diagram could be used to obtain a solution, but that to me is a pointless exercise,...I would much rather find the solution by algebraic means,..much more satisfying to do it that way.
The problem in itself is not difficult,..the mathematics required is known to the majority of school students by the time they reach the end of year 10. The problem lies in knowing how to use that knowledge,..you have the tools, but do you know how to use them?

Talking about learning the skills and knowing how to use them...
When learning differentiation/integration at school, my teachers in year 11 and 12 didn't know or couldn't tell us what it was for. Then I learnt it at uni, again the lecturers couldn't tell us what it was for. It wasn't until studying 2nd year modern (or was it classical?) physics that any of it was used. And they taught it to us again there, so those previous two goes at learning it were redundant.
They teach waaay too much crap at school.
RICK: Oh, so they are, are they? Well, tell me, Neil. Who invented the internal combustion engine? Was it Porky the Pig? No, it was Lincoln Rawls, wasn't it?! And the Theory of Relativity. Was Pythagoras a pig? No, he was a Greek, wasn't he? So tell me, Neil. You're the expert. [grabs the cups] What's the major piggie contribution to civilization?
NEIL: Ummm.... [pause, thinking]
RICK: It's bacon, isn't it? Bacon and rooling around in the mud. Look out, Michaelangelo, here comes the new piggie Renaissance!
Sorry this has little relevance to the thread - I always think of this line when I here Pythagoras' name
