Does it triangle?
For reasons that would take too long to explain, I’ve been thinking about triangles and how some combinations of lengths don’t create a valid triangle. To help me think through that I ended up making a little app where the user can adjust the length of one side at a time to get a sense of when the triangle breaks down. The app can be found here.
I’m posting this so I find this at some unknown future. So, hi future self. If you aren’t me, hi to you too.
