Envelope: Geometric Construction of an Ellipse
2017-06-17 03:00
This applet generates an ellipse as a line envelope. A moving point on a circle connects to a fixed interior point, and the perpendicular bisector of this segment is constructed. Using the Sequence command, a family of bisectors is created. As the point moves, their envelope forms an ellipse, visually demonstrating envelope concepts and ellipse properties via geometric constructions.
