teacher.desmos is not classroom.amplify.com, and after you log in, you can find your activities on the left side and the activities work the same way.

D (the center of the triangle) is the focus of a parabola with the directrix being one of the sides. So the parabola through F and G have side AC as the directirx. Points inside the FGH region are closer to the center than to sides.

Colors are cool, but attributes such as thick/thin, or long-dash/short-dash are better (imo) for addressing accessibility issues

28.07.2025 07:30 — 👍 5 🔁 0 💬 0 📌 1I think the key is the radius increases by a linear sequence, so r=theta. Or r=K * theta. There are some variations by raising theta to different powers.

Here is what I mean. This is going to work, but each vertex of the rolling triangle is going to yield a different path. Which could be cool.
