# GPT-4 Is Nonetheless Not Able to Educate Geometry — science weblog

**It Nonetheless Falls Down When Offered Contradictory Data**

Lastly I attempted to explain a proper triangle with out figuring out it as such explicitly. The triangle I had in thoughts was this one:

I started by saying:

*Suppose a triangle has three sides known as A, B, and C. A is 7 inches lengthy and B is 7 inches lengthy.*

However then I made a mistake. I ought to have stated:

*The angle between A and C is 45 levels, and so is the angle between B and C.*

However as a substitute I stated:

*The angle between A and C is 45 levels, and so is the angle between A and B.*

What I described was not a proper triangle, and actually it’s not a triangle in any respect. There isn’t a approach to attract a triangle with sides and angles as I’ve described them. I made this similar mistake when speaking to GPT-3 over the vacations, and I made a decision to repeat it as a result of GPT-3’s response had been so revealing. Any tutor or trainer has to subject college students’ errors, and there are a number of methods to do it. You may right the error; you may clarify or show why it’s an error; or you may ask college students to repeat or right themselves.

Neither GPT-3 nor GPT-4 did any of these items. As an alternative, they ran with the instance and rapidly acquired themselves into hassle.

After describing my inconceivable triangle, I requested:

*What’s the size of facet C?*

GPT-4 answered:

*To unravel this downside, we are able to use the legislation of cosines, which relates the perimeters and angles of a triangle.*

And after some detailed calculations and emerged with the reply

*The size of facet C is roughly 3.63 inches.*

“Nice!” I stated, just a little disingenuously. “Are you able to draw the triangle?” GPT answered:

*Positive! Right here’s a tough sketch of the triangle:*

*On this triangle, sides A and B are each 7 inches lengthy, and the angle between them measures 45 levels. Aspect C is the facet reverse the 45 diploma angle, and we now have simply calculated that its size is roughly 3.63 inches.*

“I don’t perceive,” I stated. “If sides A and B are each 7 inches, why does A glance a lot longer than B? And why does C look longer than B if C is barely 3.63 inches?”

Once more GPT-3 apologized, however this time it couldn’t get better:

*I apologize for any confusion brought on by the sketch. My intention was to supply a tough drawing to assist visualize the triangle, however I perceive that the proportions could also be tough to interpret.*

*To make clear, in a right-angled triangle the place two sides have equal size (as on this case with sides A and B), the hypotenuse (facet C) will probably be longer than both of the opposite two sides. Nonetheless, on this case…we discovered that it’s roughly 3.63 inches. Which means it’s shorter than both of the opposite two sides, A and B. Subsequently, the proportions within the unique sketch weren’t correct.*

I requested: “How are you going to say C is the longest facet after which say that it’s the shortest facet? And how will you say C is the hypotenuse when A is the hypotenuse within the drawing?”

GPT-4 apologized.

Then I identified: “The angle between A and B doesn’t appear like it’s 45 levels.” GPT-4 apologized once more and supplied an “up to date model” that regarded precisely the identical, besides that the angle between A and B was labeled as 45 levels when it clearly just isn’t:

I requested GPT-4 for the angle between A and C. After some calculations utilizing the legislation of cosines, GPT-4 answered: 101 levels. Then I requested for the angle between B and C. It answered 34 levels, as a result of the angles of a triangle should add to 180 levels. Then I requested how this could possibly be a proper triangle if not one of the angles was 90 levels. I requested how the angle between A and C could possibly be 101 levels when it appears to be like a lot smaller than the opposite angles. I requested it how the angle between B and C could possibly be 34 levels when it regarded for all of the world like a proper angle. And on and on.

GPT politely apologized, but it surely saved moving into circles, drawing the identical image again and again and saying contradictory issues about it. Apparently, the image was completely different than the image GPT-4 had drawn earlier than the service went down in March. That image has disappeared from GPT-4’s historical past, but when my reminiscence serves it regarded one thing like this:

It wasn’t a proper triangle in any respect, and and GPT-4 couldn’t inform me clearly if the symbols A, B, and C represented the perimeters, the angles, or the vertices.

It could appear just a little odd that GPT-4 would generate two such completely different photos from the identical immediate, but it surely makes extra sense whenever you bear in mind two issues. First, each response from ChatGPT comprises a random element. Second, no image could possibly be right, for the reason that info I provided couldn’t describe any actual triangle.

**Trigger for Fear, Trigger for Hope**

After I first proposed to put in writing about ChatGPT’s math skill in December, it could have been honest to reply that nobody had proposed to make use of ChatGPT as a math tutor.

What a distinction a couple of months have made. On Friday, *Axios* printed a narrative titled “Sal Khan explains why GPT-4 is able to be a tutor,” which reported that Newark, New Jersey, and Hobart, Indiana, had joined a pilot of a brand new product known as Khanmigo, which makes use of ChatGPT to assist tutor math. I don’t assume ChatGPT is prepared for this, however within the story Khan says that “it’s getting higher,” and “stresses that Khanmigo didn’t simply take GPT-4 out of the field — it additionally added its personal ‘secret sauce’ to assist keep away from math errors.”

I hope it really works. I hope children in Newark and Hobart aren’t battling a chatbot that may be as complicated and confused because the one which I interacted with. I hope academics in Newark and Hobart are retaining an in depth eye on the scenario. I hope the districts have a well-defined and rigorous course of for attempting and evaluating new applied sciences that use “secret sauce.”

However I don’t know, and I’m just a little apprehensive.

In the meantime, the expertise continues to evolve. Whereas the following model, GPT-4.5, is scheduled for launch in September or October, what pursuits me extra is the announcement of a plug-in that connects ChatGPT to Wolfram Alpha—an older expertise, launched in 2009, that solves math issues and helps reply questions involving math and information. That is precisely what I prompt in my January 4 article (not that anybody was seeking to me for recommendation), and it sounds very promising as a result of Wolfram Alpha is essentially constructed for math in a approach that GPT, as a language mannequin, just isn’t.

The combination of ChatGPT and Wolfram Alpha hasn’t been launched but, however it could carry us nearer to the “not-too-distant future” that I speculated about in January—a future when “we could have clever applications that may tutor college students in particular topics—applications that may converse in pure language [like ChatGPT], draw on deep and correct representations of topics like geometry [like Wolfram Alpha], and acknowledge and proper the frequent missteps and misconceptions that result in unsuitable solutions.”

Not less than I hope so. However we’ll need to see.
