This GeoGebra applet dynamically demonstrates the three positional relationships between a line and a circle: disjoint, tangent, and intersecting. By constructing a circle and a line, and comparing the distance from the center to the line with the radius, along with geometric features like intersection points and angles, it visually illustrates the connection between algebra and geometry. Ideal fo
