Geometric Construction and Locus of an Ellipsograph
2012-06-12 06:30
This example demonstrates the geometric construction and working principle of an ellipsograph, also known as the Trammel of Archimedes. By constructing two perpendicular tracks and allowing the endpoints of a segment to slide along them, the locus of any point on the segment forms an ellipse. The dynamic model integrates commands like polygons, segments, circles, and orthogonal lines, featuring an
