What does your textbook say about 4.5 Circles and Tangents?
In our day-to-day real life situations, we have seen two lines intersect at a point or do not intersect in a plane. For example, two parallel lines in a railway track, do not intersect. Whereas, grills in a window intersect. Similarly what happens when a curve and a line is given in a plane? The curve may be parabola, circle or any general curve. Similarly, what happens when we consider intersection of a line and a circle? We may get three situations as given in the following diagram Figure Figure Figure
