  You can tell it’s a triangle because of the way it is.

    How neat is that??

  that won’t work for yoda, though. for him, there is no triangle. there’s just doangle or donotangle.

  I nearly failed geometry because I didn’t understand what my instructor wanted from me.

  “Just look at it”. Visual proofs are not proofs. They’re demonstrations. For a species that is so easily fooled by things we see, visualization cannot be taken as rigorous proof.

    Hmm can you prove that

      Optical illusions?

  Even philosophy 101 can give you a ton of reasons why looking at it just isn’t enough

    How Can Mirrors Be Real If Our Eyes Aren’t Real?

  Yes but what if one side is so slightly curved that it’s invisible to the naked eye? Then your total angles would be 179.99 degrees and it’s not a triangle.

    But isn’t a curve just many angles next to one another?

    source

    • Hule@lemmy.world ⁨3⁩ ⁨months⁩ ago

      Yes, but infinitely many.

      source
    • Cethin@lemmy.zip ⁨3⁩ ⁨months⁩ ago

      From a calculus perspective, you may be able to define it as infinitely many angles infinitely close to one another, but I don’t think that’d be a particularly good definition.

  “If we can’t prove these two triangles are similar while not being congruent, the world is doomed.”

  “Oh my god. We need a 10th grader with at least a B-average, stat!”

  In one of my last CS classes, we did proofs and would use “by observation” for this kind of thing.

  I loved geometry. It made algebra make sense. Plus I had a really awesome geometry teacher. He looked like Shel Silverstein and was super pumped every day to teach math.

    I loved geometry. It’s the class where I first got experience programming. I just sat in class programming stuff on my calculator not really paying attention. I did fine in the class luckily.

    Totally unrelated, but I (30 yo) recently realized I’m almost certainly ADHD. There definitely weren’t any identifiable signs before that people should have noticed…

  Equilateral triangle. All three sides are equal length and it has three interior angles that add up to exactly 180 degrees.

  Are you telling me that “you can see this is a triangle” ??! You can see ?? How dear you say that!
