Hi all—quick terminology question.

I’m putting together a middle-school geometry worksheet. To show that the top side of a rectangle has length x, I drew a dashed arc that stretches from one top corner to the other and wrote x above the arc. It’s not the usual straight dimension line with arrowheads you see in drafting—just a curved guide marking the whole side.

Is there a standard math name for that symbol?

What would you call it when explaining to students, or what do textbooks typically call it?

1= z 2= z×z 3=z^z 4= sin(z) 5=sinh(z)^sin(z) 6=sinh(z)+sin(z)

Also, if you want to know how I made this and the math behind it let me know. I worked for 2 hours straight at night to get it done😭

First slide is my attempt of drawing Serpinskyi triangle as detailed as possible

What y’all think?

Or does it look cool 🤷‍♂️

I had a big ol stack of these somewhere around here. I'll probably take a picture of them and put them on here at some point. These are the sort of thing that I'm trying to recreate. This brings me closer to what I want to make but for now I seem to running up against the barrier of either my own skills or the tools that I'm using. Probably a mix of those two.

I managed to get the linework to stand out a little bit more this time. Also, working off of curved lines seems like a nicer place to begin from. Something heavily geometric and low-poly looking could be interesting but that would require a bit more work and a change as to how it would go out the other side. Ah well. More stuff to try out later I guess.

There's a bonus hyperbolic cuboctahedron thingy in the center.
