This example demonstrates the trajectory and shape changes of a cat moving on a ladder, involving core math concepts like curve sketching, solids or 3D shapes, quadratic equations, combinatorics, and parabolas. It utilizes GeoGebra commands such as Intersect, Vector, Segment, Ellipse, and Polygon. Suitable for high school students learning coordinate geometry, solid geometry, and graphing functions.
