Rolling Inscribed Circle Locus Demonstration

2013-01-17 12:17
This GeoGebra example demonstrates the geometric construction and locus generation of a circle rolling without slipping inside a fixed larger circle. Using Point, Segment, Circle, and Sequence commands, it builds a dynamic model of an inscribed circle rolling along the inner wall of a larger circle, illustrating the curve traced by a point on the rolling circle (such as a hypocycloid or astroid).
