This applet demonstrates the rolling motion of a regular tetrahedron on a plane. Through translations and rotations, it visualizes the geometric trajectory of the tetrahedron flipping sequentially around its edges. The animation intuitively presents the unfolding and movement patterns of solid figures in 2D space, aiding in the understanding of spatial geometry structures and rigid body transforma
