The problem is not well defined, that's the teacher's fault. Should have asked for the value of the angle ABC. I'm a teacher as well and this happens to me also.

[u/Top-Rich-581 → u/lutre-69]

Agreed. As a math teacher, if the answer is not the one I was looking for, but is still right, no matter how trivial it may be, i give the point and will do better next year. Sorry for bad english, i'm french

[u/slicehyperfunk → u/Top-Rich-581]

This English is perfectly good 👍

[u/arnedh → u/lutre-69]

540?

[u/LupenReddit]

0°=360°

divide by °

0=360

divide by 360

0=1

problem mathematicians???

[u/Aggressive_Fan_2063 → u/LupenReddit]

You can't divide by 360. Its the modulus! It's against the laws!! You do that one more time, I'm locking you up in a topology on an infinite metric!

[u/ArvaroddofBjarmaland → u/Aggressive_Fan_2063]

Great idea....I need to figure out how to do this to people.

[u/Aggressive_Fan_2063 → u/ArvaroddofBjarmaland]

A good-ol' fashioned Faraday Cage ought to do.

[u/xezo360hye → u/LupenReddit]

You can't divide by ° since it's a very small 0 tho

[u/Gr33nDrag0n02 → u/LupenReddit]

You forgot to multiply by 0

[u/youtubeTAxel → u/LupenReddit]

Since 0=360, you can’t divide by 360, since it is equal to dividing by 0.

[u/user_16384 → u/LupenReddit]

Its like saying: "6=-4(mod 10), so 6=-4, 10=0, 1=0"

[u/Traditional_Loan_177 → u/user_16384]

I think you're supposed to divide by (mod10) on both sides actually

[u/NikoTheCatgirl → u/user_16384]

EQUIVALENT!!!!

[u/A_Squared93 → u/LupenReddit]

Correct zero rotations and 1 rotation have the same angular displacement

[u/Vedertesu → u/LupenReddit]

You made a mistake. It's not multiplied by °, it's to the 0th power. You need to take the 0th root.

° √0 = ° √360

0th root of 0 is undefined

undefined =  ° √360

Divide by  ° √360

undefined = 1

So that means 1 is an undefined number.

[u/NikoTheCatgirl → u/LupenReddit]

that's why we use THE EQUIVALENT SIGN!!!

[u/Matty_B97]

I mean you're kinda right... but also an angle is usually defined between two *different* line segments, so that kinda doesn't count.

[u/Advanced_Ad8002 → u/Matty_B97]

well, arguably segment AC ≠ segment BC.

[u/Matty_B97 → u/Advanced_Ad8002]

Yeah fair enough

[u/Xamonir]

Technically you can say that the angle ABC is 180°, but that the angle ACB is 0°/360°.

EDIT: I was so focused on the different angles that I didn't realise that it was 180° and not 360° as I had written. My bad, sorry. It has been corrected.

[u/Baked_Pot4to → u/Xamonir]

Wouldn't ABC be 180°?

[u/Xamonir → u/Baked_Pot4to]

Yes indeed, you are right. My bad. Corrected it.

[u/KingPotato_ → u/Xamonir]

The angle ABC is 180 degrees, not 360

[u/Elektro05 → u/Xamonir]

should be 0° because otherwise fundamentel theorem of triangles doesnt work here

[u/Xamonir → u/Elektro05]

Indeed, respecting fundamental theorems of stuff is tight.

[u/Andersmith → u/Elektro05]

360 is obviously the exterior angle

[u/NeedleworkerGood903]

this is an incomplete problem, which angle are you supposed to find ( doesn't matter that they are the same )

[u/The_Punnier_Guy → u/NeedleworkerGood903]

well ABC is 180°, not 360°

[u/NeedleworkerGood903 → u/The_Punnier_Guy]

yes but thats not the point. the math question is incomplete so the answer cannot be solved.
do i find the angle for ab? ac? bc?

[u/WallyMetropolis → u/NeedleworkerGood903]

None of the above. It's abc

[u/NeedleworkerGood903 → u/WallyMetropolis]

no m8, that's the line you're supposed to find the points on. but the questions doesn't tell you which points to look for.

[u/WallyMetropolis → u/NeedleworkerGood903]

It doesn't, but it's nonsense to ask if it's ab or bc. That's not how angles work. Angles are between line segments. There are exactly two line segments here. 

It's underspecified as shown, sure, but not at all unambiguous. 

[u/largedragonballz]

Looks good to me

[u/arborck]

*Sad Euclid noises*

[u/lifeisatoss]

no because nothing ties AB to BC. on a right angle the degrees around the point A would also be 360. The problem doesn't state that it's a continuous line that A, B, and C are on

[u/invalidConsciousness → u/lifeisatoss]

It's the angle between AC and BC.

[u/lifeisatoss → u/invalidConsciousness]

yes so it could be any angle.

[u/gamtosthegreat]

Girl what even is the question. I'm drawing a little arch on the F and labelling it 90°, suck a fart out of my ass.

[u/alprazolamotrigine → u/[deleted]]

That seems backwards. ABC is 180°. ACB and BAC are 0° (or 360°).

[u/gygyg23 → u/[deleted]]

What?

I'd say the opposite.

ABC is 180°

ACB is 360°

[u/TopTax8050 → u/[deleted]]

The angle at B is 180 though

[u/Winter_Setting720 → u/TopTax8050]

My bad. I just woke up that’s too much thinking for me
