# 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.

I agree with Dylan.

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!

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

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

THIS MATH IS CONFUSING I AM LOST WITH ALL THIS HAHA

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

balls up with soapy suds??? nomnom nom

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

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

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.

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

ur stupid

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

I do not like math!

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

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

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

math is so freaking confusing....

....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-

@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

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.

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

^ read above

get lives

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