# How Is The Pythagorean Theorem Used Today

The Pythagorean Theorem is a simple mathematical equation with various uses today in geometry, trigonometry, architecture, and more. The equation is as follows:

a^{2} + b^{2 }= c^{2}

This only applies for a right triangle, that is, a triangle that has a 90 degree angle. C is the hypotenuse (the longest side), and A and B are the two other sides. Thus if you know A and B, you can easily calculate C by using square roots. Likewise if you know B and C or A and C.

The ability to find out this length quickly is useful in trigonometric and geometric proofs, as well as lengths for physics, and designs in architecture.

u all shuld shaddup cuz no1 carz

OMG o-o

interesting

NEVER KEPT STUPID PHOTS ON THIS SITE ITS SHAME FOR PYTHAGORAS

WHO LIVES IN A PINEAPPLE UNDER THE SEA?...SPONGEBOB SQUAREPANTS!

Hello fellow chickens

I think you all need to learn how to spell first!

get lives

^ read above

Maths is somtimes nice bt sontimes borin......

It amazes me how much time is wasted in arguing and jotting down stupid and pointless comments, rather than to try to give useful and substansive information about the subject.

@douglas:WRONG, math is used in mcdonolds o_o, so if you dont know math, you got no job lol....so LEARN IT, i dont like math either :P

....hey doods, one thing, WHAT THE HECK? math is what keeps us from dieing, and what kept us from dieing from bad stuff, and beasides, if you suck in math, get more good at it then -3-

math is so freaking confusing....

all of you (dylan and mickey) just shut up and get a life!!!

How about you all shut up and be quite as i am Pythagoras and i am still alive

hi I do not agree with some of you i dont like math much

I do not like math!

you know what's a waste of time? arguing on whether math is useful or not!

ur stupid

Yeah you guys should definitely be working on your grammer rather than math.haha

Let me just point out how pointless it is to argue over the internet. Math has seen multiple uses in modern day life. It is used to calculate taxes, used EXTENSIVELY in Science, and can be used to put multiple numbers together. Lets not leave out probability and estimation, we use it Everyday! Even a garbage man will say "We can probably hold about ____ more pounds in the truck. Just wanted to point out how much we DO use it and if you're going to argue, go on a site made specifically for that reason. I may hate math but if I'll be learning it in the Naval Academy, I had better get used to it. Unless you wanna work in Mcdonald's, you really should too.

Math is awesome and intersting, but only if the teacher doesn't give homework!

I am glad to see young puils of today, revising what i have taught.

balls up with soapy suds??? nomnom nom

maths is so dam bitching hard but stil hav 2 do it

Math is so friggen easy! that's only cuz i'm asian but whateves!! XP

the pythagoras thing is coool!!

i like it , its fFuUnN!!!

stop arguing you ffffffffrrrrrrrrreeeeaaaaakkkkkksssss!!!!!!!!! i kinda like math, kainda dnt lk it,...... so just live with that or il flush ur heads dwn the toilets,,, hahahahahahhhhhhhaaaaaaaaa!!!!!!!!!!

HI ROSA LOVE U!!!

BLACK MAN HERE LOVING MATH!!!!! BIG NERD STATUS!!!I AM SO SMART ND IVAN IS DUMB!!!!!

-DOUBLE DEE

I LOVE MATH I AM NERD ND I HAVE STRIGHT A'S IN THIS SUBJECT!!!! LOVING MATH

-BOLDER

THIS MATH IS CONFUSING I AM LOST WITH ALL THIS HAHA

math is not a waste of time i will laugh when you finally realize that you were wrong this whole time

dylan and mickey are both right. math is a waste of time. but hey, i still do it.

I totally agree with dawn and anna. Math is so important to daily life and if we didn't use it we would still be cavemen. Just because you two (dylan and mickey) cant do math doesnt mean you should criticize it!

i think you guys should try the dawn is cool therome its so good and works everytime

ithink dylan and mickey are both... WRONG!!! so just shutup

I agree with Dylan.

i think math is a wast of time

i think its very easy to learn nd it can help you with ur mulitplcations
