Have you ever heard of a hypocycloid?

No, what is that?

It's a curve made by a point on a smaller circle rolling inside a larger one.

That sounds really interesting! I’d love to learn more about it.

Root Explanation

Hypocycloid → It is formed from "hypo-" (meaning under or below) and "cycloid" (from "cyclus", meaning circle, and "eidos", meaning form or shape). The term describes a curve traced by a point on a smaller circle rolling inside a larger circle, hence the meaning of a shape that is formed under a circular motion.

Memory Tip

Think of a smaller circle rolling 'under' ('hypo-') a larger circle, creating a unique shape — that's what a hypocycloid is.
