I’m emailing this to my geometry teacher. We’re in the middle of the unit on the pythagorean theorem…

3. lechroom says:

I remember pointing out in high school that in order to find an unknown angle, we could just use a protractor. My geometry teacher informed me that the purpose of geometry wasn’t to teach us to find angles, but rather to teach us to think logically. She was not amused when I replied that it was more logical to spend five seconds reading a protractor than thirty minutes trying to remember some stupid axiom or other.

I love you.

• Peggy says:

I think your teacher was right. Why don’t you borrow a book on Logic from your library to understand what she was talking about. You are young and it is very easy to use tools rather than let your brain do some exercise.

Wish you luck in everything that you will do in life.

• you got it wrong says:

He’s right Peggy and you got it wrong. He was able to suggest a very simple solution to a complex problem which is crucial in the real world.

You are stupid for thinking that he’s teacher is right and just dismiss his solution.

• Sil says:

Now, if YOU have had paid any attention in your logic classes, you should know by now that just because someone views things differently than you it does make them stupid…

• Geek says:

I’m fairly sure that if anyone reading this thread had studied math theory beyond the level at which you are forced to in school, the more complex situations in which trigonometry are useful do become apparent… but you need to learn to walk before you can run, and Pythagoras’ theorem is only the first baby step. :)

have fun flipping burgers.

• lechroom says:

Thanks, Peggy, but I’m actually 37 and well-versed in logical thought and the fact that it has little to nothing to do with public education. Way to assume, though! ;)

• lyone says:

And how do you think protractors were invented?

Reminds me of the Math question that 90% of respondents answer wrong.
A bat and ball cost a total of \$1.10.
The bat is \$1.00 more than the ball. How much does the ball cost?

• Evan Hughes says:

\$.05

• Dawn Marie says:

The ball is 5 cents. Easy. How did so many people get it wrong?

• zachl says:

you know exactly how so many people got it wrong.

• vukodlak says:

Because they thought they could “just use a calculator” when they were taught how to set up a system of linear equations?

5. rmanflint56 says:

I hate story problems…they never have a happy ending. Let me see, .05 + (.05 + 1.00) = 1.10 – now I’ve got a headache.

6. Grendel says:

I tried using a ruler – now they want to chop my head off for treason

7. Johnny Cash says:

Assuming those are inches on the yellow triangle, and that it’s the same triangle in the red area, that ruler isn’t to scale.

8. steve says:

I’m angry at numbers. There’s too many.

9. JW says:

Try using that ruler when surveying property or measuring distances in the atmosphere or determining molecular structure. All are very practical uses of Pythagorean Theorem.

10. Kristin says:

It’s actually really cool that a^2+b^2=c^2. Way cooler than having the cleverest snarky comment on a stupid meme.

12. lyone says:

What I wonder is why this little piece is called…… “that your teacher didn’t want you to know” because all of MY teachers certainly DID want me to to know this.

13. Chris says:

I like math, but hate word problems in math. What is x, when the farmer goes to the market with 4 chickens and a cow? The answer might as well be x=6 because pigs are blue and aliens are green.
I use the pythagorean theorem all the time with my adult students and they understand it, but most of them would just grab a tape measure and “throw a line” on it to measure it. Simpler and faster in most cases.

who ever made this post got the history wrong.

Pythagreious was the first student of Thales, the first greek philosopher in the 5th century BC. Thales was famous as the first person in history to predict a solar eclipse.

Pythagreous wanted to study music to which Thales said he had to go to egypt. In the anciet world, one did not go to schools to get an education but you had to join a cult and as you advanced, you were taught secret knowlege.

Pyhagreious became a high priest in egypt for 22 years after which he returned to greece and formed his own clut based upon math. The famous theorum was their highest secret taught only to the most advanced priest of his cult and the use of it can be seen in egyptian architecture centurie before.

the cult lasted several hundred years, longer than even the current age of the United States. The cult broke up because a high priest of the pythaqgrian cult released all of their secrets, including this famous theorem. The scandal rocked the ancient world and resulted in many assasinations and panic in cults throughtout the meditarian.

Secret knowlege secured with religious vows in cults was the ancient worlds version of a patent.

this thereom was not just something someone came up with and taught.

people were killed out of revenge for making it public and people once had to become monks to even have the chance to learn it

and now kids in high school don’t give a rats ass about it
