Ellipse Tangent Loci Starter

This example demonstrates the locus of tangent lines from a moving point on an ellipse, revealing the geometric relationship between the ellipse and its tangents. Core math concepts include the definition of an ellipse, tangent properties, and locus theory. Construction highlights: Using GeoGebra commands/objects like Point, Tangent, Intersect, Midpoint; objects: c (ellipse parameter), P (moving point), f (focus), B (tangent point), A (midpoint), M (locus). Suitable for high school mathematics education to understand the formation of loci and the geometric properties of ellipses.
