Description:
Intersecting lines within a circle involve chords, secants, and tangents meeting or crossing at one or more points. Chords link two points on the circle’s circumference, while secants intersect the circle at two points, extending outside. Tangents touch the circle at a single point, forming a right angle with the radius. Analyzing these intersections aids in understanding circle-related geometry and angle relationships.
