Triangles.... lol....

[snoozyboozy]

ok...

it all started when I couldn't sleep a couple of nights ago... So I got up, played solitaire for a little while, left some shite on facebook, read the stuff in ere, still couldn't sleep...

so, naturally... I went off, found an authentic recognised IQ test and took it....

135!!!!! top 2 percent in the country and 'genius'... great stuff...

The only thing is, I know I score high on that stuff, but ONE of those points I wasn't entitled to. I feel like i've cheated... I got lucky with this one particular question.

If two cars start back to back and drive apart in a straight line for 6 miles, then they both turn left and drive for 8 miles, how far apart are the cars?

Hmmm... So you then think, the cars were 12 miles apart then drove in opposite directions again for another 8 miles each right?

So from diagonal point to point.... the distance is?

groan....

So... I guessed the answer and got it right. But I didn't KNOW the answer.

This bugs me... It led to me being wide awake at half passed one in the morning, lying in bed with a ruler, a pencil and a piece of paper and google on my mobile phone, moaning at woody that I don't quite understand the Pythagorean theory and the workings of a triangle LOL...

If one side of a triangle (right angled) is 8cm and the other is 6cm, then what is the length of the third side?? I know it's 10cm I just don't know why!!!!!!!!!!!!

So... can someone PLEASE explain to me, IN IDIOTS TERMS, how this theory is worked out.

Fanks.

Snoozy, who's a total genius but not when it comes to sodding triangles!

dunno the mathematical answer !

but i was always taught as an apprentice
in the building trade
that if you wanted to set out a wall or building square
you used a site square !!!!!!!!!!!

BUT if the doughnut labourer burnt it on the site fire
you could use what is known as the

3, 4, 5. method !!!!!!!!!!!
i.e 300mm one way then 400mm at a right angle to that,
then across the angle 500mm .
which is the same as a triangle ? ain't it

to work out an area of a triangle (or in the trade a gable)
half the length of the base,
times ( X )
the height, at the highest point

so



CLEAR AS MUD !!!!!!!!!

[snoozyboozy]

still nuffink...........


IDIOTS terms... maths is so not my thang! LOL!!!!!!!!

[Shakey]

hmm.............
pythagorean principle needed as stated.

A hypotenuse is the longest side of a right angle triangle, and the side opposite the right angle. The length of the hypotenuse of a right anglev triangle can be found using the Pythagorean theorem, which states that the square of the length of the hypotenuse equals the sum of the squares of the lengths of the other two sides.

For example, if one of the other sides has a length of 3 meters (when squared, 9 m²) and the other has a length of 4 m (when squared, 16 m²). Their squares add up to 25 m². The length of the hypotenuse is the square root of this, or 5 m.

hope that helps

wot you do is you measure the distance between the end of the short bit an' the end of the long bit and that gives you your answer. simple. an' i know i'm a genius.

as for the cars GPS should sort that bit out. ;D

[snoozyboozy]

aha... i think... cheers shakey....


and SHATAP BEAST! lol



anyway... back to shakey....

so.. on that theory... if in my case, the first side is 6cm (36cm²) and the second side is 8cm (64cm²). That adds up to 100cm²... And the square root of 100cm² is 10cm.. ?

Therefore, the distance between the two cars is 20 miles, as it's this but twice...

Now I think I've got it, I don't feel i've cheated the quiz... fankyou

BUT.. this does only work for a triangle containing a right angle right?

[Marf]

yeah that will only work for a right triangle!

[Tudderz]

Just like Uncle Albert from 'Only Fools and Horses' trying to read the ships dials...'I couldn't make head nor tails of it son'
40 an' forgot all the unnecessary crap learnt at skool many, many years ago

[RiCko23]

Im lost in here. A calculator is a great tool though for all those difficult equations....and the easy ones to if yr a lazy trollop

[bambam]

12 miles x 12 miles = 144 miles
16 miles x 16 miles = 265 miles
total = 400 miles

the square route of 400 = 20

hence 20 miles apart!

.. and I'm in the bottom 2%

but I think the clue here is to remember that when both cars turn left they are still driving in opposite directions and not parallel... that is the I.Q. bit... the rest is just bog standard maths!
