2020-03-10 00:34
This GeoGebra applet dynamically demonstrates the three positional relationships between a line and a circle: disjoint, tangent, and intersecting. By constructing lines, circles, orthogonal lines, and intersection points, and utilizing tables and text to display the real-time relationship between the distance from the center to the line and the radius, it visually reveals the geometric criteria fo
