Coordinate Geometry

This example demonstrates how to construct an ellipse by folding paper. Key mathematical concepts include the geometric properties of ellipses and coordinate geometry. Using GeoGebra commands such as Intersect, Point, PointIn, Segment, and LineBisector, the foci of the ellipse and its corresponding locus can be constructed. Suitable for high school mathematics education and students learning coordinate geometry.

GeoGebra Commands & Parameters

Intersect(xAxis, yAxis) → A
Point(c) → B
PointIn(c) → C
Segment(C, B) → a
LineBisector(a) → b
