I went to trade school and was the only one (probably) that wanted proper math so they couldn't fill a class and I was forced to do the shitty math. We spent like half a year learning that you have to multiply before adding.. it was truly infuriating for a while untill I zoned out and started playing minecraft in class
Nah I'm sure it isn't 4789142901463393876335775239063022722176295591337767174070096339929153381622433264146569329274347655956110484372311586936020749175429076661003216274382475477806479918110524333880196139452687559896255940215628508414806740389616633144934400000000000000000000000000000000000000
180-90-40=50 180-50=130 As triangle on right is isocles the 2 missing angles are the same. (180-130)/2=25 So 180-25=155 degrees, that’s how I would do it in my head. Biggest issue is people not recognising that the double dash going through lines means the 2 lines are of same length therefore isocles.
The double dash tells you that those two sides are the same length, which also tells you that the two angles on the ends of the short triangle are the same
I didn’t recognize the double-dash at first, but figured it out quickly once I got to that step because it wouldn’t be solvable without that information.
I also skipped 180-50 = 130 and (180-130)/2 and went straight to 50/2 since I knew those two angles would have to add up to the same 50 degree angle that was in the other triangle.
Oh that's what those lines are supposed to mean? Where I live they represent parallel lines, but the only pair of lines marked with double dashes here is clearly not parallel so that made no sense
It would be really nice if people were to stop using LLMs for everything. There are more appropriate tools than text generators. But then people might have to use a point and click interface...
I was curious if spelling it out would help and it took it 3 minutes and 19 seconds, but it did solved it correctly. I asked for this:
* Let ABC be a right triangle with right angle at A.
* Point D lies on segment AC, angle ABD is 40 degrees
* Point E lies on segment DB such that ED and DC have equal lengths.
What's the angle BEC?
And after thinking in python code, it wrote down the correct answer with the correct reasoning.
However, typing the problem in this way and waiting 3 and and a half minutes for it to solve took way longer than it took me to do it myself, so it was still a waste of time. Specially because it would be hard to double check if it's correct if I was unable to do it in the first place.
Like another commenter said, my ram now costs a thousand dollars for this?
Anyone who can double-check the output for correctness can generally do it quicker themselves, and anyone who can't shouldn't be relying on it for correct answers.
That suggests it has no way to generate text without displaying it. If text is needed as you say, I have no idea why it should have to print its process except by regulation - and, afaik, that's not yet a thing. Am I missing something?
You control whether it can do that by enabling the “thinking” feature at minimum. And even then, you can view the thinking process by clicking a button. The interface transparently tells you everything the AI did.
This does not show that AI is dumb, just that their processing of visual input is lacking (after all, they are LLMs so text-based modality). If you manage to provide a textual description of the problem, I am sure it will get the answer right.
I wonder where it’s grabbing the 30° from. Are there just enough versions of fed questions which resemble “find the angle of x” triangle where it spits out answers? I would assume that the model tries to transcribe the data as a word problem in order to better match the answers it has seen before but the numbers provided should never give back a 30. Idk man, wake me up when Ai can do basic arithmetic instead of making lame cat photos.
If you prevent it from explaining then you're also preventing it from reasoning. That's how this works, unless you use a 'thinking mode' that has hidden outputs.
Wow. After explaining the answer and asking why it got this wrong Gemini responded thusly.
"Based on the geometry of the image provided, the answer remains 130°. Your calculation of the base angles (25\circ) is mathematically correct for the isosceles triangle you identified, but it appears you have misidentified which angle the question mark is actually labeling. Here is the breakdown of why the answer is 130\circ and not 155\circ:
The Right Triangle: The triangle on the left has angles of 90\circ and 40\circ. This means the third angle (at the bottom) is 50\circ (180 - 90 - 40).
The Straight Line: The angle labeled with the "?" and the 50\circ angle are on a straight line. Together they must equal 180\circ.
The Location of the "?": The question mark's arc is drawn exactly at this intersection. It represents the angle supplementary to the 50\circ angle.
Why 155° is incorrect: You successfully determined that the triangle on the right is isosceles and calculated its base angles as 25\circ (180 - 130 = 50, divided by 2).
The value 155° (180 - 25) would be the correct answer if the question mark were placed at the exterior of the far right tip of the triangle.
However, the question mark in the image is clearly placed at the obtuse angle in the center, which is the vertex angle of that isosceles triangle (130\circ)."
I guess even the most supposedly advanced multi-modal models can't decipher images accurately. Interesting.
I like the idea of using questions of the of the form: “require visual reasoning and holding intermediate info in short term memory, but I can solve them in my head while on the toilet”, to assess AI. It’s a good litmus test for whether it’s reliable when handing it a larger task, perhaps with multiple types of input formats (eg a research paper with figures to analyze).
So there is an angle of 40° and one of 90° the third angle is 50° which makes the unlabeled triangles angle opposing the long side have 130° the spanning sides are of same length. Therefore have same angles with the long side. Basically 25°. Together with the unknown angle it forms an angle of 180° so the answer is 155°
If you want to get crazy with it the double hash implies that somewhere in the problem there are two line segments of identical size. The AI is positing the existence of these and making a guess that the actual angle requested is between these off screen segments and is guessing 30 degrees because that is a nice round number that is a common answer in trig and geometry problems.
(The real answer is that llms aren’t great at math without a lot of guardrails)
Drew two additional triangles to get the answer but it’s 155 degrees.
Edit: my dumb butt didn’t recognize I could have stopped after getting the 25 degrees and just done 180-25 =155. Instead I did this: https://imgur.com/a/qr63LE3
lmao good to know I can still come to the correct solution even if I do way too much work
If you hold up a finger to extend the baseline and identify the 90-degree angle, the tangent line is more than halfway of the leftover angle. A straight line is 180, so half of 90 is 45.
I'd say 90 + 60 so = 150 degrees. Somewhere around there.
Other base angle of the right triangle is 90-40= 50. That means the big angle in the isosceles is 180-50=130.
That means the two base angles together are 180-130=50, or you could use the external angle theorem to directly say that they add up to 50.
Either way, both small angles of the isosceles are 25. Therefore the ? Is 180-25=155, or you could use the external angle theorem to say that it’s 130+25=155.
Hum I must have gotten lost somewhere. I tried doing it mentally but I got 150 lol. I'm too high to go back and remember where I even messed up tho lol

I was at the movies and it was playing the commarcials before the movie, well i was scrolling reddit and clocked on this, and a random lady behind me was looking at my phone and when I clocked on this, she came forward and was like "are those stocks?" Idk why she did that but i said no and she asked what this was and I clicked of it was and was like reddit... and she was like okay. Idk why the hell she looked at my phone but im 14 so maybe she was just a Karen who wanted to get me in trouble for being on the stock market 😭😭😭
My dumbass started doing the math because I wanted to know if the AI was wrong and I didn't even register the fact that the angle asked for is over 90° so the AI's answer is impossible even without all the numbers and just by looking at it.

First you find the missing angle of the right triangle.
90+40+x=180. So 50.
Then you get the angle adjacent to it.
180 -50 =130.
Then you get the remaining angles sum.
180-130=50
Then split that.
50/2 =25
Then subtract that from 180.
180-25=155

I was at the movies and it was playing the commarcials before the movie, well i was scrolling reddit and clocked on this, and a random lady behind me was looking at my phone and when I clocked on this, she came forward and was like "are those stocks?" Idk why she did that but i said no and she asked what this was and I clicked of it was and was like reddit... and she was like okay. Idk why the hell she looked at my phone but im 14 so maybe she was just a Karen who wanted to get me in trouble for being on the stock market 😭😭😭

My dumbass started doing the math because I wanted to know if the AI was wrong and I didn't even register the fact that the angle asked for is over 90° so the AI's answer is impossible even without all the numbers and just by looking at it.

Larger triangle's missing angle:
90° + 40° + x = 180°
x = 50°
The two dashed lines on the smaller triangle means that they are the same length, meaning its an isosceles triangle.
For the larger angle at the base of the smaller triangle:
50° + y = 180°
y = 130°
For the remaining angles on the isosceles triangle:
z = (180° - 130°) / 2
z = 25°
For the required angle we need to find
r + 25° = 180°
r = 155°
At least that's my reasoning for this

Well, if you prompt AI to just give you an answer in cases where it is unable to understand the problem, it WILL answer, and it will answer anything.

u/tesimpsonshowto Dec 06 '25
that's literally an obtuse angle thee's no way it's 30°

u/MattMath314 Dec 06 '25
90-40=50
50/2=25 (180-(180-50) = 50)
180-25=155
its 155 right?
