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?
Yes, but infinitely many.
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.
that won’t work for yoda, though. for him, there is no triangle. there’s just doangle or donotangle.
Even philosophy 101 can give you a ton of reasons why looking at it just isn’t enough
How Can Triangles Be Real If Our Eyes Aren’t Real?
I nearly failed geometry because I didn’t understand what my instructor wanted from me.
“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!”
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.
In one of my last CS classes, we did proofs and would use “by observation” for this kind of thing.
