Dynamic Geometric Demonstration of Ceva's Theorem

This example demonstrates Ceva's Theorem, which states that in triangle ABC, three cevians AD, BE, and CF drawn from vertices to opposite sides are concurrent if and only if (BD/DC)·(CE/EA)·(AF/FB) = 1. The GeoGebra applet dynamically constructs the triangle, intersection points, and segments, using vectors and ratio calculations to illustrate the geometric significance of the theorem. Users can d
