Cycloid is the path a point on circle takes when it rolls on a surface. It looks simple, but has many variations. When we roll the circle over another circle, instead of a straight line, we get a much cooler looking Epicycloid. And if the circle moves around the inner circumference, rather than the outer circumference, we get a Hypocycloid.
In this article, we go through interesting facts about cycloids and play around with some interesting graphics created with them.
